a. To construct triangle ABC:
1. Draw a line segment, AB, of length 10 cm using the ruler.
2. Place the compass tip at point A and draw an arc with a radius of 10 cm above and below point B on line AB.
3. Without changing the compass width, place the compass tip at point B and draw two more arcs intersecting the previous arcs.
4. Label the points where the intersecting arcs meet as points C and D.
5. Draw a line segment, AC, connecting point A to point C using the ruler.
b. To bisect angle ACB and find point D:
1. Place the compass tip at point C, and draw an arc that intersects line segment AC on both sides.
2. Without changing the compass width, place the compass tip at point B and draw an arc that intersects the previous arc at two points (label one of these points as D).
3. Draw a line segment, CD, connecting points C and D using the ruler.
ii. Triangle CDA is an isosceles triangle because line segments CD and CA are equal in length.
Using a ruler and a pair of compass only.
a.constructa triangle ABC such that angle ABC is 90°,BA is 10cm and angle BAC is 30°. Measure BC.
b.) i bisect the angle ACB to meet BC at D.
ii what type of traingle is CDA.
