Triangle XYZ is shown.
Which triangle must be similar to triangle XYZ ?
A.) a triangle with two angles that measure 40° B.) a triangle with angles that measure 40° and 60° C.) a scalene triangle with only one angle that measures 100° D.) an isosceles triangle with only one angle that measures 40°
Two triangles are similar if their corresponding angles are congruent and the corresponding sides are
in proportion. If a triangle was to be similar to triangle XYZ, it would surely have equal angles. If two angles on the new triangle measured 40°, each, then the third angle would have to be 100°, since angles of a triangle add up to 180°. Therefore, the correct answer would be: A.) a triangle with two angles that measure 40° Ask Algebra House Comments are closed.
