Rhombus
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.
It is a 2-dimensional shape bounded by four straight sides, which meet at right angles.
A heptagon.
A Pentagon
Rhombus
Squares and rectangles have a two-dimensional shape with four sides and four right angles.
In a real star, no. In a 2-dimensional star-shape, no. In 3-dimensional star-shapes, yes, there can be.
It is a 2-dimensional shape bounded by four straight sides, which meet at right angles.
A heptagon.
A Pentagon
Yes, provided: 1. ABCD is a closed plane figure (ie a closed 2-dimensional shape) 2. A square is considered a special case of a rectangle.
uhh, a triangle?
a pentagon :) only has 2 right angles
A triangle can have a right angle, but it isn't regular if it does. Rectangles aren't regular, but have four right angles. Squares are regular quadrilaterals, and have four right angles. No other regular polygon has any right angles.
a shape with 5 sides and 2 right angles is or are a pentagon so the answer is a pentagon
The shape of 2 right angles is a square.
