The document defines and describes the different types of triangles based on their angles and sides. It states that a triangle is a three-sided polygon with three angles and vertices. Triangles are categorized as being right, acute, or obtuse angled based on whether they have one 90 degree angle, all angles less than 90 degrees, or one angle greater than 90 degrees. They are also defined as being scalene, isosceles, or equilateral based on whether their sides are all different lengths, two sides are the same length, or all three sides are the same length respectively.

Triangles
Triangles can be classified in several ways. They have three sides and three angles. Triangles are classified based on the length of sides into equilateral, isosceles, and scalene triangles. They are also classified based on angle magnitude into acute, right, and obtuse triangles. The interior is the region within the triangle boundary, while the exterior is outside the boundary. An equiangular triangle has three equal angles and is also equilateral.
Lines and angles
Two angles are complementary if their measures sum to 90 degrees. Two angles are supplementary if their measures sum to 180 degrees. Adjacent angles have a common vertex and one common side but no interior points in common, such as the angles formed by scissors. Vertically opposite angles are formed without a common side when two lines intersect. A linear pair is formed when the non-common sides of adjacent angles lie in a straight line. A transversal is a line that intersects two or more other lines at distinct points, and intersecting lines cut each other at a common point.
Triangles
There are two main ways to classify triangles: by the lengths of their sides and by the measure of their angles. For side classification, an equilateral triangle has all three sides the same length, an isosceles triangle has two sides of equal length, and a scalene triangle has all sides of different lengths. For angle classification, an acute triangle has all angles less than 90 degrees, an obtuse triangle has one angle greater than 90 degrees, and a right triangle has one 90 degree angle. Triangles can be proven congruent through various postulates and theorems including SSS, SAS, ASA, AAS, and RHS which relate congruent sides and angles.

Mathematics 7: Angles (naming, types and how to measure them)
An angle is defined as the amount of turn between two straight lines that share a common endpoint called the vertex. Angles are measured in degrees using a protractor and can be acute (between 0-90 degrees), right (90 degrees), obtuse (between 90-180 degrees), or straight (180 degrees). Angles can be named using the vertex letter and the first letters of the lines that form the angle, such as ∠BAC.
Triangles
A triangle is a polygon formed by joining three non-collinear points. Triangles can be classified based on their side lengths or angles. There are three types of triangles based on sides: equilateral (all sides equal), isosceles (two sides equal), and scalene (all sides unequal). Based on angles, triangles are right (one 90 degree angle), acute (all angles less than 90 degrees), or obtuse (one angle greater than 90 degrees). A triangle is thus defined as a three-sided polygon where the sum of the interior angles is 180 degrees.

Lines, Angles and Triangles
Lines can be straight, curved, or a combination. A line has length but no width or thickness. An angle is formed by two rays with a common endpoint. There are different types of angles including acute, right, obtuse, straight, and reflex angles. A triangle is a three-sided polygon. Triangles can be categorized based on side length as scalene, isosceles, or equilateral triangles, and based on angles as right, obtuse, or acute triangles. The Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

1. Triangles are classified based on the lengths of their sides into equilateral, isosceles, and scalene triangles or based on the measure of their interior angles into right, obtuse, and acute triangles.
2. An equilateral triangle has three sides of equal length and three interior angles that each measure 60 degrees.
3. The sum of the interior angles of any triangle is always 180 degrees.
Triangles
The document defines and classifies triangles. It states that a triangle is a three-sided polygon whose interior angles sum to 180 degrees. Triangles are classified based on side lengths as equilateral, isosceles, or scalene, and based on angle measures as acute, right, obtuse, or equiangular. The document provides examples of each type of triangle and states that determining missing angles is an important concept.
