Can you have 3 acute angles in a triangle?

An acute triangle (or acute-angled triangle) is a triangle with three acute angles (less than 90°). Acute and obtuse triangles are the two different types of oblique triangles — triangles that are not right triangles because they have no 90° angle. …

Can a triangle have all acute angles?

Yes, all triangles have at least two acute angles. Acute angles are angles that measure less than 90 degrees, while obtuse angles measure greater than…

Can a triangle have 3 different angles?

Scalene. A scalene triangle has three different angles and none of its sides are equal in length.

Can a triangle have two acute angles yes or no?

Yes, of course! we can have a triangle with two acute angles. all the obtuse-angled triangles have two acute angles in them.

Can a triangle have no acute angles?

Explanation: The 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.

What is a 3 sided triangle called?

A triangle is a 3-sided polygon sometimes (but not very commonly) called the trigon. The sides of a triangle are given special names in the case of a right triangle, with the side opposite the right angle being termed the hypotenuse and the other two sides being known as the legs.

Can a triangle have 3 acute angles in a spherical geometry?

A statement that is equivalent to the parallel postulate is that there exists a triangle whose angles add up to 180°. Since spherical geometry violates the parallel postulate, there exists no such triangle on the surface of a sphere.

Can a triangle with 3 angles equal 60?

Sal proves that the angles of an equilateral triangle are all congruent (and therefore they all measure 60°), and conversely, that triangles with all congruent angles are equilateral. Created by Sal Khan.

Which triangle is acute?

equilateral triangle
An acute triangle is a triangle in which each angle is an acute angle. Any triangle which is not acute is either a right triangle or an obtuse triangle. All acute triangle angles are less then 90 degrees. For example, an equilateral triangle is always acute, since all angles (which are 60) are all less than 90.
