a right angle

parallel sides

congruent angles

Answer 1

@ganeshie8 could you help me please?

Answer 2

@Darcey could you help me again please?

Answer 3

a right angle

Answer 4

could you explain how you got that?

Answer 5

google it youll see

Answer 6

im trying to learn not cheat

Answer 7

i was trying to help but whatever, are you in algebra?

Answer 8

no im in geometry

Answer 9

give me a second to refresh my memory. It's been a while since I took geometry.

Answer 10

ok lol thank you

Answer 11

The slope intercept formula is y=mx+b right?

Answer 12

yes

Answer 13

Since they are asking you about a triangle you can eliminate parallel sides. Parallel lines will never intercept, and the lines that make a triangle all intercept each other.

Answer 14

ok, so now we are down to three choices, congruent sides, right angle, and congruent angles

Answer 15

Now the question between the other three can all be true. When you use the formula three times to make the three different sides you will get the lengths of you triangles which can prove that the sides are congruent, congruent means equal. If it is an equilateral triangle it would also prove that all the angles are congruent. But it could also prove that the sides and angles are not all congruent, and that you end up with a right angle. So the challenge is which one of these is most true?

Answer 16

right angle?

Answer 17

it could be, but how do you know?

Answer 18

because you can prove that the sides and angles are not all congruent as you previously stated I belive

Answer 19

yay thanks so much!

Answer 22

yup
