True or False? All equilateral triangles are isosceles.

True

What is the value of y?

50*

What is statement #4 in the proof?

SD = SD

What is reason #3 in the proof?

Given

Describe an equilateral triangle by its sides and angles.

All sides are equal, all angles are equal

R, S, and T make one triangle. E, F and D make another triangle. <R = 60*, <S = 80*, <F = 60*, <D = 40*, RS = 4, and EF = 4. If the triangles are congruent, which Triangle Congruence Property was used? Which side is congruent to RT?

Yes, by ASA, FD = RT

CPCTC

What is reason #3 in the proof?

ASA

How does the hypotenuse of a triangle compare to the other legs?

The hypotenuse is the longest side

What is reason #2 in the proof?

Def. of Perpendicular

The 2 congruent angles in an isosceles triangle are called _____ angles.

Base

Given RS = ST, <RST = 7x + 2, <STU = 4x. Find the value of x.

x = 182*

What additional information do we need in order to prove these triangles congruent by HL Theorem?

AC = DC or BC = CE or AC = CE or BC = CD
