What are the height perimeter and area of a right angled trapezium with parallel sides of 10 and 13 cm with a slanted side of 5 cm?
Use Pythagoras' theorem to find the height.
The slanted side will be the hypotenuse of a right angle triangle with a base of 3 cm (the difference of the parallel sides)
52-32 = 16 and the square root of this is 4
Height = 4 cm
Perimeter = 4+10+13+5 = 32 cm
Area = 1/2*(10+13)*4 = 46 square cm

What has 4 sides 2 right angles 1 pair of parallel sides?
A right angled trapezium (trapezoid).
Does diagonals of right angled trapezium bisect each other?
No.
What does a right angled trapezoid add up to?
The angles of a trapezium add up to 360 degrees. Whether or not it is right angled is irrelevant.
The shape has 1 right angle?
A right angled triangle or a trapezium* * * * *A trapezium cannot have one right angle. If it has one it MUST have two.
How many parallel sides does a right angled trangle have?
A right angle triangle has no parallel sides
Which shape has one pair of parallel sides only?
A Right-angled Trapezium
What is a quadrilateral that has 1 pair of parallel lines and has 2 right angles?
Right-angled Trapezium
What has one pair of parallel sides of different lengths and two right angles?
Right angled trapezium
What has 4 sides 2 right angles 1 pair of parallel sides?
A right angled trapezium (trapezoid).
What is a four-sided figure with one pair of parallel lines and two right angle?
it is a right angled trapezium
How many obtuse angles in a trapezium?
Usually two, but one if it is a right-angled trapezium.
What is a 4 angled polygon that does not have the same angles?
A trapezium.
One pair of parallel sides of different lengths and 2 right angels?
A right trapezium. (A right angled triangle, sitting on one of the shorter sides, with its apex cut off by a line parallel to its base.)
What is a synonym for oblique?
Slanting or sloping.
Does diagonals of right angled trapezium bisect each other?
No.
