Question

Find the area of an isoceles triangle in which each of the equal sides measures 30cm and the third side is 48cm long

Answer 1

Answer:

An isosceles triangle is a triangle which has any two of its sides equal to each other. Also, the angles opposite these equal sides are equal. In general, a triangle is a polygon which has three sides and three vertices. The sides and angles of the triangle could vary. The types of triangles can be classified based on the sides and angles. Based on the sides, a triangle is classified into three types namely: Scalene, Isosceles and Equilateral. Whereas based on the angles, a triangle is classified into three types namely: Acute Angled, Obtuse Angled and Right Angled. In this article, we are going to discuss the isosceles triangle definition, properties, area and perimeter formulas with many solved examples.An Isosceles triangle is a triangle which has two equal sides. Also, the two angles opposite to the two equal sides are equal. In other words, we can say that “An isosceles triangle is a triangle which has two congruent sides”. Suppose in a triangle △ABC, if sides AB and AC are equal, then △ ABC is an isosceles triangle where ∠ B = ∠ C. The theorem that describes the isosceles triangle is “if the two sides of a triangle are congruent, then the angle opposite to them are also congruent”.
