Suppose △FMN≅△HQR . Which congruency statements are true? Select each correct answer. NF¯¯¯¯¯¯≅HQ¯¯¯¯¯¯ MN¯¯¯¯¯¯¯≅QR¯¯¯¯¯ ∠M≅∠Q ∠R≅∠F ∠N≅∠M QH¯¯¯¯¯¯≅MF¯¯¯¯¯¯

Answers

Answer: \overline{MN}\cong\overline{QR}

\angle{M}\cong\angle{Q}

\overline{MF}\cong\overline{QH}

Step-by-step explanation:

We know that if two triangles are congruent , then the corresponding angles and sides are congruent by CPCTC.

Given: \triangle {FMN}\cong\triangle{HQR}

Therefore , the corresponding angles and sides of \triangle {FMN}\text{ and }\triangle{HQR} are congruent.

∠F corresponds ∠H

∠M corresponds ∠Q

∠N corresponds ∠R

⇒ ∠F ≅ ∠H

∠M ≅ ∠Q

∠N ≅ ∠R

\overline{MF}\cong\overline{QH}\n\overline{MN}\cong\overline{QR}\n\overlien{FN}\cong\overline{HR}

So , from the given options, the true congruency statements are :-

\overline{MN}\cong\overline{QR}

\angle{M}\cong\angle{Q}

\overline{MF}\cong\overline{QH}
△FMN ≅ △HQR
so
MF ≅  QH
MN ≅ QR
NF  ≅ RH
and
∠F ≅ ∠H 
∠M ≅ ∠Q
∠N ≅ ∠R

Answer
MN ≅ QR
∠M ≅ ∠Q
QH ≅ MF

Can someone explain major and minor arcs in relation to circles.

Answers

A Major Arc within a circle is something that that is more than half of the circle, and therefore, larger than the minor arc. The way in which this could be used in an example is; Tony has a pizza with 8 slices, 6 of these slices are pepperoni and 2 are chilli beef. In this case, the pepperoni slices are the major arc and the chilli beef slices are the minor arc.
The Major Arc will always be bigger than the minor arc- whether this is 181 degrees to 179, or whether this is 350 degrees to 10 degrees.
The Minor Arc is always the smallest arc, and this can be explained by; Benedict has an apple pie that has 10 slices, between him and his friends, they have eaten four slices. In this case, they have eaten the 'minor arc'
There is a picture attached, and this is the examples of a major and a minor arc.

A school bus has 25 seats, with 5 rows of 5 seats. 15 students from the first grade and 5 students from the second grade travel in the bus. How many ways can the students be seated if all of the second-grade students occupy the first row?a. 25P20
b. 5P5 × 20P15
c. 5C5 × 25C14
d. 5P5 × 15P15
e. 5P5 × 25C15

Answers

Answer:

The correct option is b.

Step-by-step explanation:

It is given that the school bus has 25 seats, with 5 rows of 5 seats.

The number of students from the first grade is 15 and the number students from the second grade is 5.

The formula to arrange r items in n places is

^nP_r=(n!)/((n-r)!)

The number of seats in first row is 5 and the number students from the second grade is 5. So, the total number of arrangement is

^5P_5

The number of seats except first row is 20 and the number students from the first grade is 15. So, the total number of arrangement is

^(20)P_(15)

The total number of ways the students can be seated if all of the second-grade students occupy the first row is

^5P_5* ^(20)P_(15)

Therefore the correct option is b.

b
