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.
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.
Are Base angles of an isosceles triangle are 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.
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.
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 parallelograms squares?
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
What are necessary when proving that the opposite sides of a parallelogram are congruent?
A. Corresponding parts of similar triangles are similar.B. Alternate interior angles are supplementary.C. Alternate interior angles are congruent.D. Corresponding parts of congruent triangles are congruent
Does a rhombus have acute and obtuse angles?
Yes, a rhombus can have both acute and obtuse angles. A rhombus is a quadrilateral with all sides of equal length, but its angles can vary. Since the opposite angles of a rhombus are congruent, if one angle is acute (less than 90 degrees), then the opposite angle will also be acute. Similarly, if one angle is obtuse (greater than 90 degrees), then the opposite angle will also be obtuse.
What is the difference between a parallelagram and a rectangle?
In a parallelogram:the opposite sides are parallel and congruent,the opposite angles are congruent,the consecutive angles are supplementary,the diagonals bisect each other, anda diagonal divides it into two congruent triangles.to be simple both sides are congruent and both sides are parallel
