An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

## Does equilateral triangle have 3 acute angles?

An equilateral triangle has three acute angles. Every triangle is made up of three sides.

## Is an isosceles triangle has three acute angles?

Explanation: An equilateral triangle is also isosceles and has 3 equal acute angles ( 60o each).

## Do all triangles have 3 acute angles?

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.

## Can a triangle have 3 acute angles and why?

Not only can a triangle have three acute angles (which is very common), you can also get triangles with angles so acute that their total sum is less than 180 degrees! This happens in a negative curved space.

## What angles do triangles have?

A triangle has three angles, one at each vertex, bounded by a pair of adjacent sides.

## What is the minimum number of acute angles of a triangle can have?

2 acute angles Answer: A triangle must have at least 2 acute angles in it.

## What kind of triangle always has 3 acute angles and 3 sides the same length?

equilateral triangle Equilateral. An equilateral triangle has three equal sides and angles.

## Can a triangle have all acute angles?

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 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.

## How many angles measure less than 90 degrees in an acute triangle?

three angles Acute TriangleAn acute triangle has three angles that each measure less than 90 degrees. Equilateral TriangleAn equilateral triangle is a triangle in which all three sides are the same length.

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

## Can a triangle have a 1 degree angle?

An angle in a triangle can measure 0 ∘ 0 ^ /circ 0∘. Why some people say its true: Sure, although a 0 ∘ 0 ^ /circ 0∘ angle would make for a very flat triangle, or it could be very thin and pointy, if the top angle is the 0 ∘ 0 ^ /circ 0∘ one.

## Can a triangle have 1 acute angle?

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°.

## What kind of triangle that has 3 acute angles measuring less than 90 degrees?

Acute and obtuse triangles An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles.

## What do you call a triangle with 3 equal sides?

equilateral triangle Equilateral. An equilateral triangle has three equal sides and angles. It will always have angles of 60° in each corner.

Types of Triangles. All equilateral triangles are equiangular. All equiangular triangles are equilateral. A right triangle will have 1 right angle and 2 acute angles.

## What do you call a triangle that has more than 90 angle but less than 180 angle?

– Obtuse Angle An obtuse angle is a type of angle whose degree measurement is more than 90° but less than 180°.

## Which set of angles could be the interior angles of a triangle?

Answer: 19° ,70° and 91° only one represent the interior angle of triangle.

## Can an angle in a triangle be zero?

The zero angle is possible geometrically in a right triangle when the length of opposite side is equal to zero. Due to zero length of opposite side, the length of hypotenuse is absolutely equal to the length of hypotenuse.
