Such special properties of the isosceles triangle help us to calculate its area as well as its altitude with the help of the isosceles triangle formulas.Īrea of an Isosceles Triangle: It is the space occupied by the triangle. Thus, in an isosceles triangle, the altitude is perpendicular from the vertex which is common to the equal sides. What Are the Isosceles Triangles Formulas?Īn isosceles triangle has two sides of equal length and two equal sides join at the same angle to the base i.e. The two important formulas for isosceles triangles are the area of a triangle and the perimeter of a triangle. Various formulas for isosceles triangles are explained below. The two angles opposite to the equal sides are equal and are always acute. Allow your child to shine bright with SplashLearn.In geometry, an isosceles triangle is a triangle having two sides of equal length. But that’s precisely where you will require a great deal of patience while teaching your kid. Students may also find it a bit overwhelming to remember the properties of isosceles triangles. This game will push your child towards mastery while developing overall mathematical capabilities.

Classify Triangles : The game challenges your child to sharpen their skills by solving a series of problems involving two-dimensional shapes to identify different types of triangles.Students will choose the correct answer from the options. They will use the attributes given to determine the correct triangle and learn the characteristics of a triangle. Identify Types of Triangles : In this game, your child will identify various types of triangles.With SplashLearn, there are several games about triangles for children to try.

Therefore, perimeter of an isosceles triangle, P = 2(24) + 16 = 64 cm.

Here, a (sides) = 24 cm and b (base) = 16 cm Perimeter of an isosceles triangle = (a + a + b) cm, i.e., (2a + b) cm Example 3įind the perimeter of an isosceles triangle if the base is 16 cm and the equal sides are 24 cm each.įormula of the perimeter of an isosceles triangle, P = 2a + b Perimeter of an isosceles triangle = sum of its sides What is the perimeter of an isosceles triangle, if equal sides are ‘a’ cm each and the unequal side is ‘b’ cm? cm and a base of 6 cm?Īrea of isosceles triangle = ½ x base x height What is the height of an isosceles triangle with an area of 12 sq. Here, ‘a’ refers to the length of the equal sides of the isosceles triangle and ‘b’ refers to the length of the third unequal side. The perimeter of the isosceles triangle is given by the formula:.The area of an isosceles triangle is given by the following formula:.One example of isosceles obtuse triangle angles is 30°, 30°, and 120°. Isosceles obtuse triangle: An isosceles obtuse triangle is a triangle in which one of the three angles is obtuse (lies between 90° and 180°), and the other two acute angles are equal in measurement.Isosceles right triangle: The following is an example of a right triangle with two legs (and their corresponding angles) of equal measure.One example of the angles of an isosceles acute triangle is 50°, 50°, and 80°. Isosceles acute triangle: An isosceles acute triangle is a triangle in which all three angles are less than 90°, and at least two of its angles are equal in measurement.

Generally, isosceles triangles are classified into three different types: The sum of three angles of an isosceles triangle is always 180°.

The isosceles triangle has three acute angles, meaning that the angles are less than 90°.

In the isosceles triangle given above, the two angles ∠B and ∠C, opposite to the equal sides AB and AC are equal to each other.

In an isosceles triangle, if two sides are equal, then the angles opposite to the two sides correspond to each other and are also always equal.

Here is a list of some properties of isosceles triangles:
