Do watch all the videos to learn how to construct triangles.
To find two possible lengths
Read and try to understand Textbook 1B explanations and worked examples: pg 119 to 120.
Do watch all the videos to learn how to construct quadrilaterals.
Possible question type on perpendicular bisectors:
Construct the perpendicular bisector for line AB
(Note: Use compass and follow the steps in the video )
The point P is equidistant from A and B.
(Note: Must construct the perpendicular bisector first. Then point P will be any point on the perpendicular bisector drawn.)
Note: The point P connecting to the points A and B will form an isosceles triangle.
Possible questions type on angle bisectors:
Construct the angle bisector for angle PQR.
(Note: Use compass and follow the steps in the video )
The point Y is equidistant from PQ and QR.
(Note: Must construct the angle bisector first. Then point Y will be any point on the angle bisector drawn.)
Note: The point Y must be perpendicular to the line segments PQ and QR.
