Construction

Draw a pair of tangent to a circle of radius 5cm which are inclined to each other at an angle of 60^(@). Give steps of construction.

An image I is formed of a point object O by a mirror whose principal axis is AB as shown in figure. (a) State whether it is a convex mirror or a concave mirror . (b)Draw a ray diagra to laacate the mirror and its focus . Write down the step of construction of the ray diagram. Consider the possible two cases. (1) When distance of I from AB is more than the distance of O from AB and (2) When distance of O from AB is more than the distance of I from AB

The following sentences are the steps involved in construction of the incircle for the triangle XYZ in which /_Y =90^(@), XZ=6 cm and YZ =4 cm. Arrange them in sequential order from the first to the last. (A) Mark the foot of the perpendicular from I onto YZ as D. (B) Construct the triangle XYZ with /_ Y =90^(@),XZ=6 cm and YZ =4 cm . (C ) Draw a circle with I as the centre and ID as radius. This is the required incircle. (D) Draw the bisectors of /_ X, /_ Y and /_Z and mark their point of concurrence as I.
