About
Unit 3 Postulates and Theorems
The third unit of geometry.

Made by Maxwell L.
Triangle Sum Theorem
The sum of the angle measures of a triangle is 180°.
The measures of <A, <B and <C equals 180°.
Exterior Angle Theorem
The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote
interior angles.
m<A+m<B=m<BCD
Isosceles Triangle Theorem
If two sides of a triangle are congruent, then the angles opposite the sides are congruent.
Since AB and AC are congruent <B and <C are congruent.
Triangle Midsegment Theorem
A midsegment of a triangle is parallel to a side of the triangle, and its length is half the length of that side
BC is twice as long as DE
Side-Side-Side (SSS) Congruence Postulate
If three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.
Triangle ABC is equal to triangle DEF because the sides are equal.
I chose these theorems because they are essential to working with triangles.
