Atriangle with two congruent sides is always a 45-45-90 triangle. a. true b. false

False

Step-by-step explanation:

1) If a triangle has two congruent sides, then we are dealing with an isosceles triangle. If a triangle has two congruent sides and it is a 45º,45º,90º it's a special case of an isosceles triangle called Right Isosceles Triangle.

The Sum of its interior angles must be equal to 180º always!

2) Check it out below an example of an Isosceles Triangle. ∠E≅∠G

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
