An isosceles triangle has side lengths of 7 cm, 7 cm, and 10 cm. Therefore, the area of the isosceles triangle is 24 square cm. Thus, using this can also help us to find the height of an isosceles triangle. In this calculator, the Greek symbols (alpha) and (beta) are used for the unknown angle measures. Using the formula for the area of an isosceles triangle: Area (1/2) x base x height. ![]() Where, $l,b,h$ are the length, base, and height of the triangle respectivelyĪlso, we used the Pythagoras theorem because the height of a triangle is always perpendicular to the base and thus, divides the triangle into two right congruent triangles. Two special cases of isosceles triangles are the equilateral triangle and. Therefore, the angles will also be two equal () and the other different (), this being the angle formed by the two equal sides ( a ). The other side unequal is called the base of the triangle. What is the perimeter of this triangle How to find the side of an isosceles triangle. The isosceles triangle is a polygon of three sides with two equal sides. Hence, in order to find the height, we can use the Pythagoras theorem, hence, we will get: how to find the height of an isosceles triangle calculator. Therefore, in order to calculate the height of an isosceles triangle, we can multiply the area of the triangle by 2 and divide the product by the base of the triangle to find the required height.Īn alternate way of finding the height of an isosceles triangle is:Īs we know, the height of an isosceles triangle splits the entire triangle into two congruent triangles. Here, multiplying both sides by 2 and then, dividing both sides by $b$, we get, ![]() ![]() We will then substitute the known area and base to find the required height of the isosceles triangle.Īrea of triangle, $A = \dfrac \times b \times h$ If you know the lengths of all sides ( a, b, and c) of a triangle, you can compute its area: Calculate half of the perimeter ½ (a + b + c). If you have any 1 known you can find the other 4 unknowns. The altitude shown h is h b or, the altitude of b. We will use the definition of an isosceles triangle and the method of calculating the area of a triangle. An equilateral triangle is a special case of a triangle where all 3 sides have equal length and all 3 angles are equal to 60 degrees. Hint: Here, we are required to calculate the height of an isosceles triangle.
