How do you describe the angles and sides of each quadrilateral?
quadrilateral--a four-sided figure, any length sides, any angles trapezoid--one pair of parallel sides, any length sides, any angles parallelogram--two pairs of parallel sides, opposite sides congruent, opposite angles congruent rectangle--two pairs of parallel sides, opposite sides congruent, all angles are right angles (90 degrees) rhombus--two pairs of parallel sides, all sides congruent, opposite angles congruent square--two pairs of parallel sides, all sides congruetn, all angles are right angles (90 degrees)
What shape has all sides the same length and opposite angles are congruent?
A square
What figure has four sides each length of 30 millimeters and the opposite sides are parallel and not all of the angles are congruent?
This figure is infact a square, because a square it the only regular quadrilateral.
What shape has 2 pairs of parallel sides 2 pairs of congruent angles and has no right angles?
This is a parallelogram, opposite sides are of equal length and opposite angles are equal in size.
Are squares parallelogram?
yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent yes because a paralellogram has two sets of paralell sides and a square does too and opposite sides are equal in length and opposite angles are congruent
Are the base angles of an isosceles triangle congruent?
Yes, the base angles of an isosceles triangle are always congruent. An isosceles triangle commonly has two sides that are equal in length. The base angles are the angles opposite those two equal sides of the triangle. A geometric theorem states that if two sides of a triangle are congruent, then the angles opposite those sides are congruent. The converse is also true.
Quadrilateral with congruent sides and no right angles?
rhombus. The rhombus is a quadrilateral with all sides equal in length. It is also a parallelogram, so opposite sides are parallel and equal in length, and opposite angles are equal.
What are the properties of a equalateral triangle?
All three sides are congruent (equal in length); all three angles are congruent (same measure).All three sides are congruent (equal in length); all three angles are congruent (same measure).All three sides are congruent (equal in length); all three angles are congruent (same measure).All three sides are congruent (equal in length); all three angles are congruent (same measure).
Are the diagonals of a rectangle congruent always?
Yes. You can show this by SAS of two right triangles. Consider rectangle ABCD. AD and BC are the same length and AC and BD are the same length because opposite sides are congruent. The angles ADC and BCD are congruent since it is a rectangle and the angles are right angles. So the triangles ADC and BCD are congruent and their hypotenuses (the diagonals of the rectangles) are congruent.
Are all angles of a parallelogram congruent?
All angles of a parallelogram are not necessarily congruent. A parallelogram means that the opposite sides run in straight lines that don't intersect. An example is a rectangle or square. Length of sides DO NOT determine if opposite angles are congruent. As long as opposite sides do not intersect each other at any point (if you continue to draw the lines), then the angles diagonal from each other are the same.
Can a rectangle have a congruent opposite sides?
Yes, it normally has opposite congruent lengths and opposite congruent widths. The length of a rectangle is normally greater than its width.
I am a quadrilateral that has 4 right angles. My opposite sides are parallel and of equal length. What figure am I?
A quadrilateral with 4 right angles and opposite sides that are parallel can be either a rectangle if the adjacent sides are of different length or a square if the adjacent sides are of the same length.
