Similar figures have the same shape but not size, with the same ratio of corresponding side lengths. Congruent figures have the same shape and size. The Greek symbol Δ means figures are similar, while the symbol ≅ means figures are congruent. Similar triangles have a ratio of 3:4:5, and in congruent figures corresponding parts are equal, so EF must be 8 and BC must be 12.

Similar and congruent figures
Similar figures have the same shape but not size, with the same ratio of corresponding side lengths. Congruent figures have the same shape and size. The ≅ symbol indicates figures are similar, while the = symbol shows they are congruent. Similar triangles problems involve finding side length ratios, while congruent figure problems involve determining specific side lengths using corresponding parts of the same position between figures.

Math 9 similar triangles intro
The document is a lecture on similar triangles. It defines similar triangles as having the same shape but different sizes, and discusses how similar triangles have corresponding angles that are congruent and corresponding sides that are proportional. It provides examples of similar triangles and statements showing their similarity. It also covers using proportions of corresponding sides to solve for missing sides in similar triangles and several proportionality principles related to similar triangles, including the basic proportionality theorem involving parallel lines cutting across a triangle.
similar_triangles_in english_language.ppt
Similar triangles have the following properties:
1) Corresponding angles are equal in measure and sides are scaled by the same factor.
2) To show triangles are similar, you can either prove corresponding sides are scaled by the same factor, or show corresponding angles are equal.
3) To calculate missing sides, first find the scale factor by comparing any two pairs of corresponding sides, then multiply or divide the known side by the scale factor.
7th pre alg similarity & triangles
This document discusses similarity between shapes and triangles. It provides the following key points:
1. Two shapes are similar if corresponding angles are equal and corresponding sides are proportional. All regular polygons and rectangles can be similar or not similar depending on if they meet these criteria.
2. If two shapes are similar, one is an enlargement of the other. The scale factor represents the ratio of corresponding sides.
3. Similar triangles only require equal corresponding angles, not proportional sides. Unknown sides of similar triangles can be found using scale factors determined from corresponding sides.
4. Parallel lines drawn to the sides of a triangle form similar triangles. This property can be used to solve problems involving similar triangles.

[2] It discusses ways to prove if a quadrilateral is a parallelogram, including if opposite sides are parallel/congruent, opposite angles are congruent, or the diagonals bisect each other.
[3] It defines rectangles as parallelograms with four right angles, and notes their properties include having congruent diagonals. It also discusses rhomb
Similar Figures
The document discusses using proportions to find missing sides of similar figures. It provides an example of using a proportion to find the measure of side FG in two similar triangles where one side is 12/5 and the other is 24 mm. It also discusses properties of similar figures, including corresponding angles being congruent and corresponding sides being proportional. Finally, it provides an example of a rectangle ABCD being enlarged by a scale factor of 3/4 to create a similar rectangle EFGH and asks how the ratio of the areas compares to the ratio of corresponding sides.
Basics of geometry
Points, lines, and planes are the undefined terms in geometry that form its foundations. A point has no dimensions and marks a location in space, a line extends in one dimension, and a plane extends in two dimensions. The basic elements of 2D space are points, lines, line segments, rays, angles, and their intersections. Rays and angles are defined using points and lines, with rays having a starting point and angles consisting of two rays with the same starting point.
Similar Triangles Notes
1) Congruent and similar triangles can be used to simplify design and calculations. Congruent triangles have equal sides and angles, while similar triangles have the same shape but not necessarily the same size.
2) Corresponding sides and angles of similar triangles have the same ratios. Ratios can be used to determine unknown side lengths.
3) Triangles are similar if two angles are congruent (AA similarity) or if all three sides are proportional (SSS similarity).

- Points, lines, and planes are the undefined terms that form the foundations of geometry.
- A point has no dimension, a line has one dimension and extends indefinitely, and a plane has two dimensions and extends indefinitely.
- Geometric figures can intersect if they share one or more points in common. The intersection of two lines is a point, a line and plane intersect at a point, and two planes intersect along a line.
- Angles are classified as acute, right, obtuse or straight based on their measure.
Geometry Evaluation 4 grade
1. This document is a math term evaluation for a student that assesses their understanding of solid shapes, angles, and geometric figures.
2. It includes multiple choice questions testing the student's knowledge of properties of prisms, pyramids, cones, parallel and perpendicular lines, different types of angles, calculating area, and identifying elements of circles.
3. The student is evaluated on their ability to recognize, draw, classify shapes and apply numerical concepts and measurements.
Text 10.5 similar congruent polygons
Two polygons are similar if they have the same shape but not necessarily the same size. Congruent polygons have the same shape and the same size. The document provides examples of finding corresponding sides and angles of similar and congruent polygons. It also gives examples of determining if two polygons are similar by checking if the ratios of corresponding sides are equal.
MATH4-Q3-WEEK-4.pptx
This document provides a lesson on relating triangles and quadrilaterals. It defines triangles and quadrilaterals as polygons and notes they are related based on their sides and interior angles. Triangles have a total interior angle measure of 180 degrees, while quadrilaterals have a total interior angle measure of 360 degrees. The document then discusses different types of quadrilaterals like parallelograms, rectangles, squares, rhombi, and trapezoids, defining their properties. It provides examples of how one quadrilateral relates to another based on attributes like opposite side lengths and angles.
Lesson 35
Students will learn to identify similar and congruent polygons. Similar polygons have the same shape but different sizes, with corresponding angles that are equal and sides that are proportional. Congruent polygons have the same shape and size, with both corresponding angles and sides that are equal. Examples are provided to demonstrate side-side-side similarity, angle-angle-angle similarity, finding missing sides, and using scale factors to determine actual lengths and widths from a drawing.

- 1. Similar and Congruent Figures
- 2. Similar and Congruent Figures • Similar figures have the same shape, but not the same size. They must have the same ratio of side lengths • Congruent figures have the same shape and the same size • Corresponding parts are the sides or angles that have the same position.
- 3. • The symbol means that the shapes are similar • The symbol means that the shapes are congruent
