Answer:

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

The perimeter of a triangle is 34cm. What are the lengths of the sides if the first side is twice the length of the second side

dybincka [34]

Answer:

the first side of the triangle: x

the other side of the triangle: 2x

the third side of the triangle: x+2

4x=32

x=8

2*8=16

Verify that (a+b)+c = a+ (b+c) by taking a = -8 , b = (-8/11) , c = (-8/12)

gogolik [260]

Answer:

Step-by-step explanation:

$(-8+-\frac{8}{11} ) + (-\frac{8}{12}) = -\frac{96}{11} + (-\frac{2}{3}) = -\frac{288 + 22}{33}) = -\frac{310}{33}\\ (-8) + (-\frac{8}{11} + (-\frac{2}{3})) = (-8) + (-\frac{46}{33})= -\frac{310}{33}$
