Answer:

1. Perpendicular

2. Isosceles

3. Never

Step-by-step explanation:

1. AC ⊥ BD because diameter of a square are perpendicular bisector of each other.

2. In Δ AOB , By using pythagoras : AB² = OA² + OB² .......( 1 )

In Δ COB , By using pythagoras : BC² = OC² + OB²  ..........( 2 )

But, OA = OC because both are radius of same circle

So, by using equations ( 1 ) and ( 2 ), We get AB = BC ≠ AC

⇒ ABC is a triangle having two equal sides so ABC is an isosceles triangle.

3. The side can never be equal to radius of circle because the side of the square will be chord for the circle and in a circle chord can never be equal to its radius

Can I please get help? Find M1 and M2
marishachu [46]

Answer:

m∠1 = 110° and m∠2 = 70°

Step-by-step explanation:

m∠1 = 110° since vertical angles

To find m∠2, m∠1 and m∠2 must add to 180°

m∠1 + m∠2 = 180°

110° + m∠2 = 180°

m∠2 = 70°

Sally says, "If it's sunny, I will go to the park. When I go to the park, I go down the slide."
nikitadnepr [17]

Answer:

I can conclude that Sally went down the slide. I used deductive reasoning to get my answer. Sally said that if it was sunny, she would go to the park. She also said that if she does go to the park, she will go down the slide. Since Sally did go to the park, I know that she did go down the slide. Based on the information I have, I can use deductive reasoning to get to my answer.

A triangle has a side length of 15 inches and 30 inches.It also has angels that measures 45 and 20.Which of the following identi
Alika [10]
I am assuming that you will need to do Pythagorus Theorem to find the 3rd side length. If thats the case then you will need to do the following formula : a^2 + b^2 = <span>√(c) 
So 15^2 + 30^2 = </span>√(c)
= 33.5 inches

The third angle would be 115 because 180 - 45 - 20 = 115

I hope this helped.
