Answer 4

well, you simply need to recall the definition of an isosceles triangle

Answer 5

and you may need to pick the more general form since there are actually 2 forms of iso tris to pick from

Answer 6

Is it C?

Answer 7

C?

Answer 8

what is the definition of an iso tri?

Answer 9

Are you sure?

Answer 10

I believe isosceles triangles have 2 sides that are equal and one that isn't?

Answer 11

@amistre64

Answer 12

the 'one that isnt' part is not accurate

Answer 13

therefore an equilateral is also an iso tri

Answer 14

Oh..it's at least 2 sides are congruent.

Answer 15

so the solution here is a bit of a conundrum

Answer 16

I got the two sides equal part so it can't be c right

A

Answer 23

No, not quite.

Answer 24

A has 3 sides congruent..we're looking for 2.

Answer 25

D

Answer 26

See those slashes?

Two of the sides each have 1 slash, which means those two sides are congruent..

Answer 27

Yep, you got it.

Answer 28

Thanks

Answer 29

In reality, the definition of an isosceles triangle is a triangle that has at least two congruent sides. @amistre64 mentioned this above.
Therefore, any triangle that has only 2 or all 3 congruent sides is an isosceles triangle.
With that in mind, both A and D are isosceles triangles.
