Draw angles with the following given parts? a) I vertex, IJ and IK are the arms, b) X vertex, XZ and XY are the arms, c) Q vertex, PQ, RQ are the arms.

Name the angles, vertex and arms of the angles from the figure.

Draw a circle, and show the following parts in a circle. a) vec(AB) diameter, b) vec(XY) segment, c) OPQ sector, d) vec(CD) chord.

Draw figures for the following statement. “If the two arms of one angle are respectively perpendicular to the two arms of another angle then the two angles are either equal or supplementary”.

Classify the following triangles according to their (i) sides and (ii) angles. (2) Write the six elements (i.e. the 3 sides and 3 angles) of Delta ABC . (3) Write the side opposite to vertex Q in Delta PQR . (4) Write the angle opposite to side bar(LM) in Delta LMN . (5) Write the vertex opposite to side bar(RT) in Delta RST . If we consider triangles in terms of both sides and angles we can have the following types of triangles:

Fill in the Blanks : The opposite angles which have same vertex and have no common arm are called ___ angles.

The angles having a common arm and common vertex are called_____angles.

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
