Are triangles PRU and STQ congruent? Question 2 options:
denis23 [38]

PRU and STQ are not congruent because they aren’t the same size.

No, because they aren’t the same size.

<u>Step-by-step explanation:</u>

Both PRU and STQ triangles aren't in the same size, So it is not congruent. Triangles are congruent if two pairs of corresponding angles and a couple of inverse sides are equivalent in the two triangles.

If there are two sets of corresponding angles and a couple of comparing inverse sides that are not equal in measure, at that point the triangles are not congruent.

Out of 18 people in a room, 2 have red hair. What is the probability that a person picked at random from the room does NOT have
Mariana [72]

Answer :

  • Total number of people in the room = 18

  • Number of people with red hair = 2

  • Number of people not with red hair = 18 - 2 = 16

  • Probability of picking a person who doesn't have red hair = \sf\dfrac{Number\:of\:favourable\:outcomes}{Total\:outcomes}

Probability = 16/18

Reduce the fraction with 2

Probability = 8/9

Choose the correct word that completes each statement about inscribing a square in a circle.
Anna11 [10]

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
