Module 5 Lesson 1: Investigating Angles of Triangles Characteristics
... 10. Since the two sides are equal, the two angles are also so they are both 4x + 9. The one with the box is 90 so the set up is 4x + 9 + 4x + 9 + 90 = 180. Answer: x = 9 11. Since this triangle is equilateral, all the sides are equal. Pick the two that have “w” in them and set them = so w+14 = 4w – ...

Lesson 23: Base Angles of Isosceles Triangles
... “base angles of an isosceles triangle are congruent” if we already have the isosceles triangle with the congruent sides stated in the given. Otherwise, if we do not know that we have an isosceles triangle already then we can state… “In a triangle, angles opposite equal sides are equal” as well as “I ...

... To show that two triangles are congruent using the definition of congruent polygons, as we did in the proof at the end of section 4.1, we need to show that all ____ 6 pairs of corresponding parts are congruent. The postulates introduced below allow us to prove triangles congruent using only ____ ...
