## Are all isosceles triangles also equilateral are all equilateral triangles also isosceles Are both of these statements correct or neither explain?

Explanation: Isosceles = at least TWO sides of equal length. Equilateral = ALL THREE sides of equal length. Yes, all equilateral triangles are also isosceles.

## Is it true that some isosceles triangles are not equilateral?

No. Isosceles triangles are those that have two sides to be of equal length, while equilateral triangles are those that have all three sides of equal length.

## Is every equiangular triangle isosceles?

Every equilateral triangle is also an isosceles triangle, so any two sides that are equal have equal opposite angles. Therefore, since all three sides of an equilateral triangle are equal, all three angles are equal, too.

## Is it possible to have a right isosceles triangle?

An isosceles right triangle is an isosceles triangle and a right triangle. This means that it has two congruent sides and one right angle. Therefore, the two congruent sides must be the legs. Therefore, we only need one of the three lengths to determine the other two lengths of the sides of an isosceles right triangle.

## How do you find the side of an isosceles triangle?

To find an unknown side of a triangle, you must know the length of other two sides and/or the altitude. To find the unknown base of an isosceles triangle, using the following formula: 2 * sqrt(L^2 – A^2), where L is the length of the other two legs and A is the altitude of the triangle.

## How do you find the hypotenuse of an isosceles triangle?

How do I find the hypotenuse of isosceles right triangle?

1. Find the length of one of the non-hypotenuse sides.
2. Square the length of the side.
3. Double the result of the previous step.
4. Square root the result of step 3. This is the length of the hypotenuse.

## What is the rule for perimeter of an isosceles triangle?

The length of the two equal sides is 5 cm. We know that the formula to calculate the perimeter of an isosceles triangle is P = 2a + b units. Therefore, the perimeter of an isosceles triangle is 16 cm.

## What is the circumference of an isosceles triangle?

To calculate the perimeter of an isosceles triangle, the expression 2s + b is used, where s represents the length of the two congruent sides and b represents the length of the base.

## What are the side lengths of an isosceles triangle?

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
