Question

I'm working with congruent triangles. It's a triangle with 2 sides that each equal 8 inches. The bottom side is unknkown. So sides xy and xz are both 8 inche and zy is unknown. Angle x is 60 degrees. Question 8 says Find the measure of angle y. Question 9 says find the measure of side yz. Thanks! There's an attachment in comments below

Answer 1

which number you looking at?

Answer 2

8 and 9

Answer 3

ok, that is an isosceles triangle, congruent is for 2 or more triangles that are the same.
isosceles has two sides equal length,

Answer 4

The property of a triangle with 2 same side lengths, is the angles across from them are also the same measure angles

Angle Y = Angle Z

Answer 5

and a triangle totals 3 angles to 180, so you can figure the angles

180 = 60 + x + x

just used x as the angle value for both y and z

2x = 120
x=60

all three angles are 60

Answer 6

so it is really an equilateral triangle, all sides the same length

Answer 7

So the bottom side is also 8 inches, since it'seems equilateral?

Answer 8

Since it's equilateral I meant to say

Answer 9

yes it is, all 3 angles are 60, and the sides are all same length

Answer 10

Okay, Thanks!

Answer 11

welcome
