## Which set of angles Cannot form a triangle?

The angles of the triangle always sum to 180 degrees.

…

Therefore the angles has to be less than 180 degrees.

So, any set of three angles that add up to 180 degrees can form a triangle..

## What is an angle of a triangle?

The angle of a triangle is the space formed between two side lengths of a triangle. A triangle contains interior angles and exterior angles. Interior angles are three angles found inside a triangle. Exterior angles are formed when the sides of a triangle are extended to infinity.

## Could a triangle have 3 acute angles?

A triangle where all three internal angles are acute (less than 90 degrees). … In any triangle, two of the interior angles are always acute (less than 90 degrees)*, so there are three possibilities for the third angle: Less than 90° – all three angles are acute and so the triangle is acute.

## Does a triangle have one right angle?

A triangle that has one right angle is called a right triangle. … The angles in an equilateral triangle are always 60°. When a triangle has two congruent sides it is called an isosceles triangle. The angles opposite to the two sides of the same length are congruent.

## Can a triangle have 1 right angle?

A right triangle (American English) or right-angled triangle (British English) is a triangle in which one angle is a right angle (that is, a 90-degree angle). The side opposite the right angle is called the hypotenuse (side c in the figure). …

## Can you have a triangle with 2 obtuse angles?

No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.

## What are the 3 sides of a right triangle?

In a right triangle, the hypotenuse is the longest side, an “opposite” side is the one across from a given angle, and an “adjacent” side is next to a given angle. We use special words to describe the sides of right triangles.

## Can a triangle have 2 right angles?

No, a triangle can never have 2 right angles. A triangle has exactly 3 sides and the sum of interior angles sum up to 180°. So, if a triangle has two right angles, the third angle will have to be 0 degrees which means the third side will overlap with the other side.

## Does a triangle have 4 right angles?

The “3,4,5 Triangle” has a right angle in it. (Draw one if you ever need a right angle!) And, like all triangles, the three angles always add up to 180°.

## Can a triangle have all angles less than 60 degree?

No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°.

## Can a triangle have all its angles acute?

A triangle can never have only one acute angle. If a triangle has 1 acute angle, the other angles will be either right angles or obtuse angles which is not possible as the sum of interior angles of a triangle is always 180°. So, every triangle needs to have at least 2 acute angles.

## Can a triangle have one obtuse and right angle?

Answer and Explanation: No, a triangle cannot have an obtuse and a right angle.

## Why can a triangle only have one right angle?

A triangle can’t have 2 angles with measures of 90 degrees or more, since the measures of the interior angles of a triangle add to 180. Thus in any triangle, at most 1 angle has measure 90 or more, and the other two angles have to be acute.

## How many right angles does a triangle have?

one right angle1 Answer. Daniel L. A right triangle has only one right angle.

## What is the greatest number of right angles in a triangle?

Explanation: A triangle has 180o as the sum of all its internal angles, no more, no less. If one angle is 90o , then you can have two 45o angles, one 30o and a 60o , an 81o and a 9o – pretty much any combination of numbers adding up to 90 to make the total 90+90=180 .
