please prove Theorem 5.8 (Converse to the Isosceles Triangle Theorem). If two angles of a triangle...
Question 1. Prove the converse of the isosceles triangie theorem: if a triangle has two angles equal, then the sides opporite the oqual angles are equal
prove that a triangle is isosceles if and only if two altitudes are congruent. prove both ways
prove this theorem Theorem 10.25. Every parallelogram has the following properties. (a) Each diagonal cuts it into a pair of congruent triangles. (b) Both pairs of opposite sides are congruent. (C) Both pairs of opposite angles are congruent. (d) Its diagonals bisect each other.
Show all work please!!! 9) Prove the converse of the Pythagorean theorem: If the three sides satisfy a2 + b2 = c2 then the triangle is a right triangle.
4. a) Draw an example of two non congruent triangles that satisfy the following conditions. If not possible, explain why. (1) The two triangles have congruent corresponding angles. (ul) The two triangles have congruent corresponding angles, and one pair of sides (not corresponding sides) congruent. () The two triangles have congruent corresponding angles, and two pairs of sides (not corresponding sides) congruent. b) (i) is the statement "If A ABC A DEF, then 2CAB ELFED", true or false? Clearly explain...
NOTE: Please do not copy paste already existing answers. Q) Q) Prove the Converse to the Similar Triangles Theorem (Theorem 5.3.4) Theorem 5.3.4 (Converse to Similar Triangles Theorem). If△ABC and △DEF are two triangles such that AB/ DE = AC/ DF = BC/ EF, then △ABC ~ △DEF. Prove the following Angle-Side-Angle criterion for similarity: If AABC and ADEF are two triangles such that LCA B-LFDE, LABC-LDEF, and DE = r . AB, then AABCADEF with common ratio r Prove...
A If Angle ABD is congruent to Angle EEB, then two pairs of triangles are congruent in this figure. CBB Concepts used: Isosceles triangle, Angles opposite congruent sides are congruent, base angles are congruent, triangle congruence theorems, and CPCTC Color-code all corresponding congruent parts with the same color . Label congruent angles using letters such as xe and y°, etc. Name the two triangles that are congruent State which triangle congruence theorems/corollaries apply. Show work on the figure that verifies...

Can anyone help me prove the theorem 49 by using the following hint( Circle)? Here is Theorem 39, can't use like right angles are 90 degrees, or that triangles are 180 degrees. Strong Right Angle Theorem 49. All right angles are congruer Consequently, a right angle is congruent to another angle if and only if the other angle is also a right angle.) Since you have already proven Theorem 39, it remains only to prove the converse: i f LX...
