Question

2 sides and 3 angles of a quadrilateral that is to be constructed are given. How can you find the location of the 4th point? [1 Mark]

• A. Using angle and length
• B. Using only length
• C. Using two angles
• D. Using two arcs

Answer 1

The correct option is C Using two angles

Let’s draw a rough sketch of a quadrilateral using 2 sides and 3 angles.
Let’s start by drawing a triangle ABC using the given two sides AB, BC and one angle ∠ABC.
Now we have two angle ∠BAD and ∠BCD remaining to draw.
So, the fourth point D is located using lines made by any two angles.
