GET 102 GEOMETRIC CONSTRUCTION: POLYGONS AND TANGENCY Objective Question

Question

When constructing a curve tangential to two perpendicular lines (Page 17) with a given radius R, what is the first construction action?
Options
A Draw the required curve from center O.
B With centers B and C, draw arcs with radius R to intersect at O.
C With center A and radius R, draw arcs to cut lines at B and C.
Correct Answer
D Extend the perpendicular lines to meet at O.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 17, step 1 for 'To Construct a Curve Tangential to two Perpendicular lines' states: 'With centre A and radius R, draw arcs to cut lines at B and C.'

Hint

The initial step often involves using the given radius and reference points.
