If PR bisects ∠SRT and U is the midpoint of RT.

Part 1) Triangle UQR Is an obtuse isosceles triangle

Part 2) Triangle RST is a equilateral triangle

Part 3) Triangle SRQ is a right scalene triangle

Part 4) Triangle PRT Is an obtuse isosceles triangle

Part 5) Triangle TQU is a equilateral triangle

Part 6) Triangle PQT is a right scalene triangle

Step-by-step explanation:

The complete question is:

If PR bisects ∠SRT and U is the midpoint of RT, classify each triangle by its angles and sides

Triangle UQR

Triangle RST

Triangle SRQ

Triangle PRT

Triangle TQU

Triangle PQT

The picture of the question in the attached figure

Part 1) Triangle UQR

we know that

PR bisects ∠SRT

That means

we have

---> is given

so

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle UQR

so

Triangle UQR is a  

Remember that

An isosceles triangle has two equal sides and two equal interior angles

so

Classify

By its angles is an obtuse triangle (has an interior angle greater than 90 degrees)

By its sides is an isosceles triangle (has two equal sides)

therefore

Triangle UQR Is an obtuse isosceles triangle

Part 2) Triangle RST

we know that

---> because U is the midpoint of RT

----> because PR bisects ∠SRT

so

Classify

By its angles is an acute triangle ( interior angles less than 90 degrees)

By its sides is an equilateral triangle (has three equal sides)

therefore

Triangle RST is a equilateral triangle

Note: An equilateral triangle is subtended to be an acute triangle, because the measure of the interior angles is always 60 degrees

Part 3) Triangle SRQ

we know that

Triangle SRQ is a

Classify

By its angles is a right triangle (has an interior angle equal to 90 degrees)

By its sides is a scalene triangle (has three different sides)

Note: If any triangle has three different interior angles, then the triangle has three different length sides

therefore

Triangle SRQ is a right scalene triangle

Part 4) Triangle PRT

Find the length side QR

Applying the Pythagorean Theorem in the right triangle SRQ

Find the length side PQ

Applying the Pythagorean Theorem in the right triangle PQT

The length sides of triangle PRT are

The interior angle of triangle PRT are

Classify

By its angles is an obtuse triangle (has an interior angle greater than 90 degrees)

By its sides is an isosceles triangle (has two equal sides)

therefore

Triangle PRT Is an obtuse isosceles triangle

Part 5) Triangle TQU

Find the measure of angle TUQ

we know that

----> by supplementary angles (form a linear pair)

Find the measure of angle TQU

we know that

----> by complementary angles

----> see part 1)

so

The interior angle of triangle TQU are

Note: If a triangle has three equal interior angles, then the triangle has three equal sides (QT=QU=TU=8 m)

Classify

Triangle TQU is a equilateral triangle

Note: An equilateral triangle is subtended to be an acute triangle, because the measure of the interior angles is always 60 degrees

Part 6) Triangle PQT

we know that

Triangle PQT and Triangle RQS are congruent by SSS postulate

so

The interior angle of triangle PQT are

The length sides of triangle PQT are

Classify

By its angles is a right triangle (has an interior angle equal to 90 degrees)

By its sides is a scalene triangle (has three different sides)

Note: If any triangle has three different interior angles, then the triangle has three different length sides

therefore

Triangle PQT is a right scalene triangle

to find the total number of combinations, multiply the quantity of each item by each other:

2 pairs of shoes x 3 pairs of shorts = 6 different combinations.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
