No, not necessarily. A parallelogram can have all sides equal, but still not be a square.

A triangle with all equal angles is called?

An EQUILATERAL Triangle. An ISOSCELES Triangle is two equal sides and two equal angles. A RIGHT-ANGLED Triangle has ONE right angle (90 degrees) A SCALENE Triangle has neither equal sides nor equal angles.


What is a triangle with 1 right angle called?

A Right- Angled triangle. Also Equilatertal ; the three sides are of equal length, and the three angles are all 60 degrees. Isosceles ; two sides of equal lnegth, and two angles of equal size. Scalene ; all three sides are unequal in length, and all three angles are different. In all cases the sum on the three interior angles equals 180 degrees.


Are the angles of a rhombus all equal?

A rhombus looks like a lopsided square, or a diamond shape. It is a parallelogram with four equal sides. The angles of a rhombus do not all need to be equal BUT opposite angles of a rhombus ARE equal. If you were to "straighten it up" and make all the angles equal at right angles, it would be a square. A rhombus with four right angles is a square.


Does a parallelogram have four right angles?

Not necessarily. A parallelogram is a quadrilateral with 2 sets of 2 parallel sides. Only rectangles and squares have right angles as all four angles - a rectangle is a "special" parallelogram that has all four angles equal; a square is a "special" rectangle that has all four sides of equal length.


What parallelogram has all angles equal?

A rectangle has four angles of 90° each, also known as right angles. The special case is the square, which is a rectangle with four equal sides.

All angles are right angles but all sides are not equal?

You don't tell us enough information. In a square, there are four sides and four angles. The sides are all equal and the angles are all right angles. In a rectangle, there are four sides and four angles The opposite sides are equal and the angles are all right angles. There is no other shape in which all angles are right angles.

Classify the triangle by its angles and by its sides?

All angles equal = all sides equal = equilateral. Two angles equal = two sides equal = isosceles. All angles different = all sides different = scalene. An isosceles or scalene triangle may be right-angled or obtuse-angled if one of its angles is a right angle or obtuse angle (respectively).


What quadrilateral has all sides congruent but does not have any right angles?

It is a rhombus that has 4 equal sides but no right angles.


What has 4 sides all of its sides are equal all of its angles are right angles?

A pyrimid.. maybe? It's a square.


What has 4 equal sides its opposite sides are parallel and its angles may be right angles?

The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.


What has 4 equal sides its opposite sides are parallel and its angles may be right angles.?

The shape you are looking for is a quadrilateral. If you have a square, all angles MUST be right angles. A parallelogram can also have 4 equal sides in length and parallel sides, but a parallelogram doesn't have right angles.


What is a parallelogram where all 4 sides are equal and the opposite sides are parallel?

All "parallelograms" have opposite sides that are parallel. If all four sides have an equal length and the angles are not all right angles, it is a rhombus. If there is any right angle, then they are all right angles and the parallelogram is a square.(note : it is not possible for a quadrilateral to have four equal sides without being one of these parallelograms.)


What is the difference between squares rhombuses and rectangles?

Squares have four sides of equal length and four right angles.Rhombuses (rhombi) have four sides of equal length but the angles are not right angles. Rectangles have four right angles but the sides are not all of the same length.
