a right angled triangle.
They can have some (or all) equal angles. A rectangle, for example, has all four angles equal but, because its sides are not the same measure, it is not a regular shape.
It always has 4 equal sides but not 4 equal angles because it has 2 equal opposite acute angles and 2 equal opposite obtuse angles. The 4 interior angles add up to 360 degrees
Rhombus = 4 equal sides Rectangle = 4 equal angles Square = 4 equal sides and 4 equal angles Rhomboid = unequal adjacent sides and angles
quadrilaterals
Squares
All right angles will be equal as they are all 90O. Shapes that have 4 right angles will be rectangles (which include squares).
Squares
Regular shapes have equal side lengths and equal angles
A square is a regular polygon with 4 equal sides and 4 equal interior angles.
it is the square
All 4 sided shapes each equal to 360 degrees in angles
An equilateral triangle.
Various shapes do. The most obvious is a square, if you are looking for the 4 sides to be equal and the 4 angles to be equal. You can also have a rectangle or a parallelogram or a diamond shape and any arrangement of 4 sides for a shape.More generally ,it is known as a quadrilateral (a polygon with four sides and four angles).
That's three different shapes: a rectangle, a rhombus and a trapezoid respectively.
A square will have 4 sides that are all the same length, and 4 angles that are 90 degrees each. Other shapes will have 4 sides, but they may be of different lengths. Other shapes will have 4 equal sides, but not 4 angles of 90 degrees.
