Which of the following is true for the adjacent angles of a parallelogram?
Which of the following quadilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles?
Rhombus, is a quadrilaterals has two pairs of adjacent sides equal and diagonals intersecting at right angles.
Given a rhombus RICE where
RE = 13, Ol = 5 OC = 12
In a rhombus,
Diagonals bisect each other
Also,
All sides of a rhombus are equal.
RI = RE
x = 5
∴ x = 5, y = 12 and z =13

State the name of a regular polygon of 6 sides.
Find the measure of each exterior angle of a regular polygon of 9 sides.
The sides of a pentagon are produced in order. Which of the following is the sum of its exterior angles?
ABCD is a quadrilateral. If AC and BD bisect each other, what is ABCD?
A _______ is both ‘equiangular’ and ‘equilateral’.
A _________ has all the properties of a parallelogram and also that of a kite.
A simple closed curve made up of only line segments is called a ________.
A _________ is a quadrilateral whose opposite sides are parallel.
We have sum of adjacent angles equal to 180, so x+100=180x=80
RENT is a rectangle. Its diagonals meet at O. Find x, if OR = 2x + 4 and OT = 3x + 1.
2x+4 = 3x+1 gives x = 3
A triangle has zero diagonals.Diagonals must be created across vertices in a polygon, but the vertices must not be adjacent to one another. A triangle has only adjacent vertices.
Find the angle measure x in the following figure:
We have angle sum of pentagon=(52)*180 =540. Since it is a regular pentagon all angles are equal. So the sum is 5x. So each angle measures x = 540/5 = 108º
