Answer:
True choices are 1, 2, 5
Step-by-step explanation:
As per diagram, the circles are equal.
<u>Since the distance AB is the radius of both circles:</u>
- AB = AC = BC = BD = AD = r
<u>So the answer choices:</u>
1. AC = BC
- Correct, both equal to r
2. AC = BD
- Correct, both equal to r
3. CD = AB
- Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3
4. ABCD is a square
- Incorrect. ACBD is rhombus
5. ABD is an equilateral triangle
- Correct, all three sides are equal to r
6. CD = AB + AB
- Incorrect as CD = AB√3
