The angle between the legs is called the "vertex angle". The angles containing the base as a side are called the "base angles". Note: The base angles in an isosceles triangle are of the same measure. An equilateral triangle has three congruent sides. An equilateral triangle may also be called a "regular" triangle.
A "regular" polygon has all equal sides and all equal angles. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. A right triangle has one right angle. A "box" is used to indicate the location of the right angle.
Explanation : An isosceles triangle always has two equal angles. Report an Error. Triangle ABC is isosceles x and y are positive integers. Possible Answers: The two quantities are equal. Correct answer: Quantity B is greater. Explanation : Since we are given expressions for the two congruent angles of the isosceles triangle, we can set the expressions equal to see how x relates to y. Possible Answers:. Correct answer:. Explanation : We know that an isosceles triangel has two equal sides and thus two equal angles opposite those equal sides.
