 # Quick Answer: Do All Triangles Have At Least 2 Acute Angles?

## How many acute angles does every triangle have?

three acute anglesAn 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 is the least amount of acute angles that a triangle can have?

twoThe least number of acute angles that a triangle can have is 2 . As we cannot have more than one right angle or obtuse angle, we have only two or three acute angles in a triangle.

## Can a triangle have 2 right angles?

Answer and Explanation: Because of the fact that the sum of the three interior angles of a triangle must be 180 degrees, a triangle could not have two right angles.

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

A triangle cannot have neither all the angles less than 60 degree nor greater than 60 degrees. All the angles in a triangle can never be less than 60 nor greater than 60. However all the angles can be acute ,whether only two of them.

## 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°. Hence, it will not be a triangle.

## What are the 7 types of triangles?

To learn about and construct the seven types of triangles that exist in the world: equilateral, right isosceles, obtuse isosceles, acute isosceles, right scalene, obtuse scalene, and acute scalene.

## How many triangles have at least 2 acute angles?

All triangles have atleast two acute angles.In acute triangles all three are acute angles; (30°,70°,80°), (60°,60°,60°)Right angle triangles and obtuse triangles have atleast two acute angles; (30°,60°,90°), (45°,45°,90°), (30°,50°,100°), (35°,35°,110°)

## Is it possible for a triangle to 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.

## Can a triangle have 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°.

## Which set of angles can form a triangle?

A triangle is classified by its angles and by the number of congruent sides. A triangle that has three acute angels is called an acute triangle. A triangle that has one right angle is called a right triangle. A triangle that has one obtuse angle is called an obtuse triangle.

## Can 1 acute and 2 obtuse form a triangle?

A right triangle will have 1 right angle and 2 acute angles. An obtuse triangle will have 1 obtuse triangle and 2 acute angles.

## Can a triangle have both an acute and right angle?

Question 945360: A triangle cannot have both an acute angle and a right angle? In a right triangle, BOTH of the other angles MUST be acute. An obtuse angle (greater than 90 degrees) would make the sum of the angles greater than 180 degrees, which is impossible.
