Question

1. maria claims all isosceles triangles are similar. which statement best describes marias claim? a. marias claim is incorrect because isosceles triangles have two equal sides, and similar triangles cannot have equal sides. b. marias claim is incorrect because the angles of isosceles triangles are not always congruent. c. marias claim is correct because all isosceles triangles have two equal sides and one congruent angle. d. marias claim is correct because all isosceles triangles have three congruent angles.

Explanation:

Similar triangles have equal - corresponding angles and proportional sides. Isosceles triangles have two equal sides. The angles of isosceles triangles are not always congruent. For example, an isosceles triangle can have angles 30 - 30 - 120 and another 40 - 40 - 100. So not all isosceles triangles are similar.

Answer:

A. Maria's claim is incorrect because isosceles triangles have two equal sides, and similar triangles cannot have equal sides.
