Can we draw an isosceles triangle of the same area with base 5 cm?

Solution: There are two ways of drawing a triangle similar to isosceles triangle, whose base is 5 cm and height 4 cm. First you can find the other two sides using Pythagoras theorem and then find of each side and construct the triangle. Let other two equal sides of triangle be x cm.

What are the legs of an isosceles triangle?

In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.

### Does isosceles triangle equal 180?

The sum of three angles of an isosceles triangle is always 180°, which means we can find out the third angle of a triangle if the two angles of an isosceles triangle are known.

What is the length of the leg of an isosceles triangle?

The leg of the isosceles triangle is 5 dm, its height is 20 cm longer than the base. Calculate base length z. In an isosceles triangle, the equal sides are 2/3 of the length of the base. Determine the measure of the base angles.

What is the base of a right isosceles triangle?

As the two sides are equal in this triangle, the unequal side is called the base of the triangle. The angles opposite to the two equal sides of the triangle is always equal. The altitude of an isosceles triangle is measured from the base to the vertex (topmost) of the triangle. A right isosceles triangle has the third angle as 90 degrees.

#### How do you know if an isosceles triangle is acute?

The isosceles triangle can be acute if the two angles opposite to the legs are equal and are less than 90 degrees (acute angle). A right isosceles triangle has two equal sides, wherein one of the two equal sides act as perpendicular and another one as a base of the triangle.

#### How to find the perimeter of an isosceles right triangle?

The perimeter of an isosceles right triangle is the sum of all the sides of an isosceles right triangle. Suppose the two equal sides are a. Using Pythagoras theorem the unequal side is found to be a√2. Question 1: Find the area of an isosceles triangle given b = 12 cm and h = 17 cm?
