One angles less than a right angles?
Acute angle
Do triangles have at least 2 acute angles?
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
Are the angles in a pentagon greater or less than a right angle?

What is a name for a figure with 4 equal sides 2 angles less than right angles and 2 angles greater than right angle?

Which type of angle is greater than a right angle?
A right angle measures 90°. There are three angles that have greater measurement than a right angle. They are:Obtuse angles - They are angles that measure between 90° and 180°, but not exactly 90° and 180°. In other words, they measure less than 180° but greater than 90°.Straight angle - It is an angle that measure exactly 180°.Reflex angles - They are angles that measure greater than 180°.
One angles less than a right angles?
Acute angle
How many angles are less than a right angle?
Angles greater than 0 but less than 90 degrees are acute angles.
How are right angles like acute angles?
An acute angle is an angle that is less than 90 degrees.
Do triangles have at least 2 acute angles?
Yes. The sum of the angles in a triangle is 180° All angles in a triangle must be greater than 0° which means that the sum of any two angles must be less than 180° If two angles are right angles (90°), their sum is 180° which is not less than 180°; thus at most one angle can be a right angle. If one angle is a right angle and another is an obtuse angle (greater than 90°), then their sum is greater than 180°, which is not less than 180°; thus there can be at most one of a right angle and an obtuse angle. If two angles are obtuse angles, their sum is greater than 180°, which is not less than 180°; thus there can be at most one obtuse angle. If there is at most one right angle or an obtuse angle, there must be at least two acute angles.
What is an angle of less than 45 degrees?
Angles less than 90 = actute Angles of 90 = right angle Angles more than 90 = obtuse Angles more than 180 = reflex
A triangle with all angles less than a right angle?
An acute triangle is a triangle with all angles smaller than a 90 degree right angle.
Are the angles in a pentagon greater or less than a right angle?
greater than
Are acute angles and right angles different?
Yes, acute angles and right angles are different. An acute angle is less than 90 degrees - a right angle is exactly 90 degrees.
Does a rectanglehave at least two angles less or two angles greater than a right angle?
All of the angles in a rectangle are right angles.
How many angles less than a right angle does a pentagon have?
It can have up to 3 such angles.
How are acute angle and obtuse angle different?
Acute angles are angles that are less than 90 degrees. Obtuse angles are angles that are more then 90 degrees and less then 180 degrees Any angle that is 90 degrees is a right angle. == == == ==
Which figures have some angles that has less than right angle?
A triangle and any irregular polygon with 4 or more sides can have some angles that are lass than right angle.
