# How many obtuse angles can an isosceles triangle have?

## How many obtuse angles can an isosceles triangle have?

one obtuse angle
An isosceles triangle can have only one obtuse angle.

## Can an isosceles triangle be obtuse angles?

Types of Triangles by Length In an isosceles triangle, two sides are the same length. An isosceles triangle may be right, obtuse, or acute (see below).

How many obtuse angle are possible in a triangle?

An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles. Since a triangle’s angles must sum to 180° in Euclidean geometry, no Euclidean triangle can have more than one obtuse angle.

How many sides does a obtuse isosceles triangle have?

An obtuse triangle may be either isosceles (two equal sides and two equal angles) or scalene (no equal sides or angles). An obtuse triangle has only one inscribed square.

### What is obtuse-angled isosceles triangle?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. Hence, if one angle of the triangle is obtuse, then the other two angles with always be acute.

### How many acute angles are in the isosceles triangle?

two acute angles
Isosceles. An isosceles triangle can be drawn in many different ways. It can be drawn to have two equal sides and two equal angles or with two acute angles and one obtuse angle.

How many equal angles are in an isosceles triangle?

two equal angles
An isosceles triangle therefore has both two equal sides and two equal angles.

What is an obtuse isosceles angle?

Isosceles triangles always have two equivalent interior angles, and all three interior angles of any triangle always have a sum of degrees. Since this is an obtuse isosceles triangle, the two missing angles must be acute angles.

## Does isosceles triangle have 2 equal angles?

An isosceles triangle therefore has both two equal sides and two equal angles. The name derives from the Greek iso (same) and skelos (leg).

## What are the rules of an isosceles triangle?

Rules for Isosceles and Equilateral Triangles. The given triangle is an equilateral, it is said to be equiangular. The two sides of the triangle are said to be congruent, and then the two sides of the triangles are the base angles of an isosceles triangles. The triangle is said to be an equiangular, it is represented as equilateral.

What are facts about the isosceles triangle?

The equal sides of an isosceles triangle are known as the ‘legs.’ The third and unequal side of an isosceles triangle is known as the ‘base.’ The angle made by the two equal sides of an isosceles triangle is known as the ‘ vertex angle.’ The angles that involve the base of an isosceles triangle are known as the ‘base angles.’

How do you find the angle of an obtuse triangle?

Since every triangle has a measurement of 180 degrees, a triangle can only have one obtuse angle. You can calculate an obtuse triangle using the lengths of the triangle’s sides. Square the length of both sides of the triangle that intersect to create the obtuse angle, and add the squares together.
