Answer: The triangles are not similar.
Explanation:
Similar triangles have similar properties.
- Their sides are the same ratio, but don't have to be the same size.
- Their corresponding angles are equal
- Same shape
To find if the two triangles given are similar, solve each for the missing angle.
All three angle measures of a triangle add to 180 degrees, so subtract the other two angle measures from 180 to obtain the third:
180 - 39 - 43 = 98
180 - 39 - 58 = 83
So, the angle measures of the first triangle are 39 - 58 - 83, and the angle measures of the second triangle are 39 - 43 - 98.
Because the angles are different, the triangles do not have the same shape, nor are their corresponding angles equal.
They are not similar.
