All rights reserved. Each of the three sides of a triangle is called a “leg” of the triangle, and the longest leg of a right triangle is called the “hypotenuse.” The angle opposite the hypotenuse will always be 90°, the largest of the three angles. And we know that having three equal legs of a triangle means we have an equilateral triangle.

(E) Page created - November 25, 2013. You will get this wrong answer if to △ABC\triangle ABC△ABC and trapezoid ABEDABEDABED you apply the theorem which states that if two figures are similar, then the ratio of their areas equals the square of their scale factor. That is. In any triangle, the measure of the interior angles is 180°. 19.01.2021 . Though the side measurements may change, an isosceles triangle will always have one 90° angle and two 45° angles. (D) (B)   1:3\ \ 1:3  1:3 The measures of the angles in a triangle add to. Other questions may also ask you to find the area, surface area, or volume of an abstract figure or a real-life object.
