Question

Match the following
$\begin{array}{ccc}1.& \text{Right angle}& \text{exact}{180}^{\circ }\\ 2.& \text{Obtuse angle}& \text{complementary}\\ 3.& \text{No. of faces in a cube}& \text{Exact 90}\\ 4.& \text{Straight angle}& Six\\ 5.& \text{Sum of adjacent angles is}{90}^{\circ }& \text{More than}{180}^{\circ }\text{less than}{360}^{\circ }\\ 6.& \text{Sum of 2 angles is}{180}^{\circ }& \text{More than}{90}^{\circ }<{180}^{\circ }\\ 7.& \text{Angle around a point}& Supplimentary\\ 8.& \text{Reflex angle}& {360}^{\circ }\end{array}$

Answer 1

Right angle is exactly ${90}^{\circ }$

Obtuse angle is more than ${90}^{\circ }$ and less than ${180}^{\circ }$

No. of faces in a cube is six

A straight angle is exactly ${180}^{\circ }$

If the sum of two adjacent angles is ${90}^{\circ }$, then the angles are complementary

If the sum of two adjacent angles is ${180}^{\circ }$, then the angles are supplimentary

The angle around a point is ${360}^{\circ }$

Reflex angle is more than ${180}^{\circ }$ and less than ${360}^{\circ }$
