Draw an angle `/_AOB=100^@`. With the same vertex O, draw `/_BOC=80^@` such that `bar(OB)` is common to two anglen.

Draw an angle /_AOB=40^@ . With the same vertex 'O' draw /_BOC=50^@ , taking bar(OB) is initial ray as shown in the figure. Since the sum of these angles is 90^@ they together form a right angle. Take another pair 60^@ and 50^@ and join in the same way. Do they form complementary angles? Why? Why not?

To draw a pair of tangents to a circle which are inclined to each other at an angle of 60^(@) it is required to draw the tangents at the end points of two radii inclined at an angle of ………

Two parabolas have the same vertex and equal lengh of latus rectum such that their axes are at right angle. Prove that the common tangents touch each at the end of latus rectum.

Can you construct the triangle ABC with the same measures by changing the base angle angleC instead of angleB ? Draw a rough sketch and construct it

In the adjacent figure DeltaABC , bar(OB), bar(OC) are the angle bisectors of angleB, angleC respectively Intersect at 'O'. angleBOC =130^@ . If bar(OB)=bar(OC) , then find angleA, angleABC, angleACB .

Statement (X): Two adjacent angles be complementaryStatement (Y): adjacent angles need not be a same vertex. Statement (Z): Each angle in any pair of complementary angles is always acute

Draw two different rectangles having the same perimeter. Compare their areas. Are they same? Can you draw two different squares having the same perimeter.

In the figure anglePOQ and angle PQR have common vertex O and common arm OP but anglePOQ,angle PQR are not adjacent angles give reason

Draw to different rectangles having the same perimeter. Compare their areas Are they same? Can you draw two different square having the same perimeter.
