WebIsosceles triangle theorem can be proved by using the congruence properties and properties of an isosceles triangle. An isosceles triangle can be drawn, followed by constructing its … The base angles of an isosceles triangle are the same in measure. Refer to triangle ABC below. AB ≅AC so triangle ABC is isosceles. ABC can be divided into two congruent triangles by drawing line segment AD, which is also the height of triangle ABC. Using the Pythagorean Theorem where l is the length of the … See more For an isosceles triangle with only two congruent sides, the congruent sides are called legs. The third side is called the base. The angle opposite the base is called the vertex angle, and the angles opposite the legs are … See more The height of an isosceles triangle is the perpendicular line segment drawn from base of the triangle to the opposing vertex. Using the … See more When the base angles of an isosceles triangle are 45°, the triangle is a special triangle called a 45°-45°-90° triangle. The length of the base, called the hypotenuse of the triangle, is … See more The altitude of an isosceles triangle is also a line of symmetry. Leg AB reflects across altitude AD to leg AC. Similarly, leg AC reflects to leg AB. … See more fluid build up ear
