Quadrilateral

Question 1

What is area and perimeter of parallogram

Answer 1

AREA =B*H PERIMETER=2(A+B)
A=side and b=base

Area of parallagram when opposite sides are equal
Area =ab* sin theta

Question 2

area of trapezium and preimeter

Answer 2

area =½ × (a + b) × h
Area =median* height
perimeter= add all sides

Isoclee trapezium h=

Question 3

area of rhombus and perimeter
And relation between side and diagonal

In radius formula

Answer 3

½ × d1 × d2 where d=diagonals
perimeter=4a

Area =a^2 Sin theta

2~ 4a^2=d1^2+d2^2

3- r= d1d2 /2root d1^2+d2^2

R= A/S

Question 4

Cyclic quadrilateral when sides abcd
And diagonals p and q

Answer 4

Pq=ac+b+d

Question 5

Parallogram diagonal formula

Answer 5

Root a^2+b^2 -2ab cos theta

Question 6

Rhombus side formula

Answer 6

Side=root d1/2 whole square +d2/2 whole square

Question 7

Cyclic quadrilateral when 90 angle pair relationshi

Answer 7

a^2+c^2=b^2+d^2

Question 8

Height formula for isosceles trapezium:

Answer 8

h= square root c ^2−( a−b/2 )^2

The difference of the bases (a−b)
gives the length of the segment outside the shorter base.

Areas in trapezium if 4 triangles then both opposite trapezium while adding have same area
