Which best explains whether or not all isosceles triangles are similar? All isosceles triangles are similar. Two angles within each triangle are always congruent. All isosceles triangles are similar. The triangle sum theorem states that the sum of the angles in a triangle is 180°. Therefore, the third angle can always be determined. All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle. All isosceles triangles are not similar. Given only the vertex angle of an isosceles triangle, there is not enough information to determine the measures of the base angles. Therefore, it is not possible to determine if the base angles of one isosceles triangle are congruent to the base angles of another.
Answers
An isosceles triangle has (no less than) two equivalent side lengths. Suppose every one of the three side lengths are equivalent, the triangle is additionally symmetrical.
Isosceles triangles are extremely useful in deciding obscure edges. In an isosceles triangle, the two equivalent sides are called legs, and the staying side is known as the base.
Answer: All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
Step-by-step explanation:
Consider a isosceles triangle having pair of congruent angles as 45° and another isosceles triangle having pair of congruent angles as 60°
Then, by using angle sum property the remaining angle in first triangle = 90° and the remaining angle in second triangle = 60°
Hence, they are not similar because no two angles of one triangle is congruent to two angles of another triangle.
Therefore, All isosceles triangles are not similar. The pair of congruent angles within one triangle is not necessarily congruent to the pair of congruent angles within the other triangle.
