What is a 5 sided shape?

pentagonA five-sided shape is called a pentagon.

A six-sided shape is a hexagon, a seven-sided shape a heptagon, while an octagon has eight sides….

What is a shape with 2 right angles?

The quadrilateral that can have only two right angles is a trapezoid. Not all trapezoids have right angles, but we can construct one that does.

Which shape has only right angles?

rectangleA rectangle is a four-sided shape where every angle is a right angle (90°). Also opposite sides are parallel and of equal length.

What shape has 4 sides and 3 right angles?

Name of QuadrilateralDescriptionRectangle2 pairs of parallel sides. 4 right angles (90°). Opposite sides are parallel and congruent. All angles are congruent.Square4 congruent sides. 4 right angles (90°). Opposite sides are parallel. All angles are congruent.TrapezoidOnly one pair of opposite sides is parallel.1 more row

Can a parallelogram have exactly 3 right angles?

Quadrilaterals have 4 sides and 4 angles. The exterior angles of any convex polygon (ie no interior angle is less than 180 degrees) add up to 360 degrees ( 4 right angles). … Therefore, if 3 internal angles are right angles, the 4th angle must also be a right angle. So no quadrilaterals have exactly 3 right angles.

What shape does not have a right angle?

A rhombus is defined as a parallelogram with four equal sides. Is a rhombus always a rectangle? No, because a rhombus does not have to have 4 right angles. Kites have two pairs of adjacent sides that are equal.

Can a trapezoid have two right angles?

A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. … An acute trapezoid has two adjacent acute angles on its longer base edge, while an obtuse trapezoid has one acute and one obtuse angle on each base.

Does a diamond shape have right angles?

But a diamond also has four equal sides and right angles at the corners.

Can a parallelogram have exactly 2 right angles?

A parallelogram is a quadrilateral with 2 pair of opposite sides parallel. A rectangle is a special parallelogram that has 4 right angles. A square is a special rectangle that has all four sides congruent. … The angle between these two sides could be a right angle, but there would only be one right angle in the kite.

What is a shape with 3 right angles?

So a pentagon has a maximum of three right angles, as shown.

How many right angles does a cross have?

There are 8 right angles within the white section, here are then 4 more within the red section of the cross and 4 more in the corners.

Can a triangle have 3 right angles?

No, real, triangle can have three right angles. The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.

What is a 9 sided shape called?

enneagonIn geometry, a nonagon (/ˈnɒnəɡɒn/) or enneagon (/ˈɛniəɡɒn/) is a nine-sided polygon or 9-gon.

What are the 7 Quadrilaterals?


Can a kite have a right angle?

Thus the right kite is a convex quadrilateral and has two opposite right angles. If there are exactly two right angles, each must be between sides of different lengths. All right kites are bicentric quadrilaterals (quadrilaterals with both a circumcircle and an incircle), since all kites have an incircle.
