Acute triangles. They can have three angles, all less than 90 degrees (total is 180 degrees).
Shapes with more than three sides must have angles of 90 degrees or more because the total of their angles must be 360 degrees (quadrilaterals) or more.

What shapes have right angles in?
A square and a rectangle have 4 interior right angles also a right angle triangle has 1 right angle of 90 degrees
Which shapes angles are all right angles?
A square shape for example has 4 right angles and a right angle is 90 degrees.
What polygon with no right angles?
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
What shape has two acute angles?
There are many possible shapes with two acute angles.
How many angles are less than a right angle?
Angles greater than 0 but less than 90 degrees are acute angles.
Shapes with angles smaller than a right angle?
Acute angles
Which angles of the parallelogram are greater than a right angle?
One pair of opposite angle is greater than a right angle.

Which shapes angles are all right angles?
A square shape for example has 4 right angles and a right angle is 90 degrees.
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°.
How many angles greater than a right angle does this triangle have?
An obtuse triangle has 1 angle greater than a right angle and 2 acute angles. Its 3 interior angles add up to 180 degrees.
Do triangles have a right angles?
Of all the triangular shapes, only a right angle triangle has one right angle (90 degrees).
Are the angles in a pentagon greater or less than a right angle?
greater than
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.
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 polygon with no right angles?
All polygons can have right angles except for circle and ovulated shapes. The only 'regular polygon' that has a right angle is the quadrilateral.
Can a right angle be a obtuse angle?
No, it cannot be because they are two different things right angle is 90° and obtuse angles are angles greater than 90° Thanks, shanzay
