The document shows there is a relationship between Mersenne primes and perfect numbers - if 2n - 1 is a Mersenne prime, then 2n-1 x 2n-1 will be a perfect number. This relationship is demonstrated for the first few Mersenne primes. The document encourages further research on Mersenne primes and perfect numbers.

5.5 And 5.6 Rambo Notes
The document provides information about properties of parallelograms, rhombuses, rectangles, and squares. It states that parallelograms have opposite angles and sides that are equal, and diagonals that bisect each other. Rhombuses additionally have diagonals that are perpendicular bisectors of each other and that bisect the angles, dividing the rhombus into four equal right triangles. Rectangles have diagonals that are congruent and two lines of reflectional symmetry. Squares have four 90 degree angles and diagonals that bisect each other and the angles, dividing the square into four equal isosceles triangles of 45, 45, 90 degrees.
5.3 And 5.4 Rambo Notes
The document provides information about properties of kites, trapezoids, triangles, and midsegments. It defines key properties such as:
- Kites have two pairs of congruent adjacent sides and perpendicular diagonals.
- Trapezoids have one pair of parallel sides and two sets of supplementary angles. Isoceles trapezoids have congruent base angles.
- Midsegments of triangles and trapezoids are parallel to the third side and have a length that is half of the third side.
- Triangles can be divided into smaller congruent triangles using midsegments.
Ch. 5 Notes
Students will be taking notes on Chapter 5 of their geometry textbook. They are to read the chapter sections and complete any investigations or gold boxes. They should take notes on each section separately so additional class notes can be added. Students will make a chart comparing the properties of kites, trapezoids, isosceles trapezoids, parallelograms, rectangles, squares, and rhombi including their side lengths, angle measures, parallel parts, and diagonals. The class will have the option to learn the material through the teacher or by being assigned into groups to teach sections to each other.

4.4 And 4.5 Congruence
This document provides an overview of congruence shortcuts for triangles. It discusses the different ways triangles can be proven congruent, including:
- SAS (Side-Angle-Side)
- ASA (Angle-Side-Angle)
- SSS (Side-Side-Side)
- AAA (Angle-Angle-Angle)
It explains that triangles are congruent if three parts (sides or angles) correspond and are equal in measure. The order of the parts must also match between the two triangles.
4.3 Triangle Inequaltites
The document discusses triangle inequalities and properties of triangles. It asks questions about determining the largest and smallest angles of a triangle based on side lengths, ordering sides from greatest to least, and properties of exterior angles. Specifically, it notes that the exterior angle is equal to the sum of the remote interior angles.
Review 4.1 To 4.2

This document discusses properties of isosceles and equilateral triangles. It reminds the reader that isosceles triangles have two equal sides and two equal angles, and equilateral triangles are a special type of isosceles triangle that has three equal sides and three equal angles. The document emphasizes that isosceles and equilateral triangles have predictable angle and side properties that can be useful for solving problems, especially on standardized tests.
4.1 Triangle Sum
This document provides geometry warm up problems focusing on triangle sum conjecture. It reviews that triangles have three sides and three angles. It asks students to recall that the sum of the angles in a triangle is always 180 degrees from prior investigation on page 199. Students are instructed to do a paragraph proof on page 200 using this information. The document also discusses using one triangle to find a missing angle in another triangle, and emphasizes that the order of angles matters.
Midpoint Notes
The document discusses finding the midpoint of a segment on a coordinate plane. It explains that the midpoint is the middle point between two endpoints that is equidistant from each end. While a picture can help visualize the midpoint, the coordinate midpoint property states that the midpoint can be found mathematically by taking the average of the x-coordinates and the average of the y-coordinates of the two endpoints. An example is provided to demonstrate finding the midpoint using this property rather than confusing it with the slope formula, which uses subtraction.
Review Of 2.5, 2.6
