What is a triangle with an angle that is more than 90 degrees?

An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees. In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°.

Which triangle has an angle greater than 90?

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.

What is a triangle with a 90 degree angle called?

From Wikipedia, the free encyclopedia. A right triangle (American English) or right-angled triangle (British), or more formally an orthogonal triangle (Ancient Greek: ὀρθόςγωνία, lit. 'upright angle'), is a triangle in which one angle is a right angle (that is, a 90-degree angle).

Can a triangle have more than one angle greater than 90?

When an angle of a triangle is 90 degrees, the triangle cannot have an obtuse angle. The other two must each be less than 90 degrees (90 deg + 89 deg + 1 deg = 180 deg). Note that the other two angles can be any combination but both would be acute angles (smaller than 90 degrees).

Are all angles of triangle ABC smaller than 90 degrees?

In an obtuse triangle, if one angle measures more than 90°, then the sum of the remaining two angles is less than 90°. Here, the triangle ABC is an obtuse triangle, as ∠A measures more than 90 degrees. Since, ∠A is 120 degrees, the sum of ∠B and ∠C will be less than 90° degrees.

Are all triangles 180 degrees?

The three interior angles of a triangle will always have a sum of 180°. A triangle cannot have an individual angle measure of 180°, because then the other two angles would not exist (180°+0°+0°). The three angles of a triangle need to combine to 180°.

What is an oblique triangle?

An oblique triangle is any triangle that is not a right triangle. It could be an acute triangle (all threee angles of the triangle are less than right angles) or it could be an obtuse triangle (one of the three angles is greater than a right angle).

What angles form a triangle?

Classifying Triangles by Angles

Triangles can also be classified by their angles. In an acute triangle all three angles are acute (less than 90 degrees). A right triangle contains one right angle and two acute angles. And an obtuse triangle contains one obtuse angle (greater than 90 degrees) and two acute angles.

Can a triangle have more than one right angle?

Ans- No a triangle cannot have more than one right angle as if there are 2 right angles the their sum will be 180° and the third angle will exceed the sum. Therefore the construction is not possible.

Can a triangle have 3 right angles?

In Spherical Geometry, a triangle can have three right angles!

Which angle is smaller than 90 degrees?

An acute angle is an angle less than 90°. An obtuse angle is an angle between 90C and 180°. A reflex angle is an angle between 180° and 360°.

What angle is less than 90?

Acute angles measure less than 90 degrees. ... Obtuse angles measure more than 90 degrees.

What type of triangle has 3 angles measuring less than 90?

A scalene triangle has three angles less than 90 degrees.

Does a triangle equal 90?

A right triangle has one angle equal to 90 degrees. A right triangle can also be an isosceles triangle--which means that it has two sides that are equal. A right isosceles triangle has a 90-degree angle and two 45-degree angles. ... One of the most famous is the "3, 4, 5 triangle."

Does a triangle equal 360?

A triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle.

Can a triangle have more than 180?

The angle sum of a triangle is greater than 180° and less than 540°. The area of a triangle is proportional to the excess of its angle sum over 180°. Two triangles with the same angle sum are equal in area.
