Question

A triangle has interior angles measuring 40 and 52. Which triangle are similar to this triangle? select true or false for each triangle.

Answer 1

The first 2 are false, the second 2 are both true.  Because all the angles in a triangle have to add up to equal 180, then 40 + 52 + 88 = 180.  Therefore, the combinations of 52 and 88 and 40 and 88 fit correctly.  92 doesn't fit at all.  It's too big.

Answer 2

The three angles of a triangle need to equal 180 degrees.
 If you have a triangle with 40 and 52, then the third angle is 180 - 40 - 52 = 88 degrees.
 

Any triangle that has at least two of the three angles ( 40 , 52 and 88) will be similar

1. FALSE
2. FALSE
3. TRUE
4. TRUE
