By CHRISTOPHER CAVIN

Math Response

What is the slope of the line shown?

Type answer here

Deg^°

Rad

Multiple Choice

Are the two lines shown parallel? Explain.

Yes, because they have the same slopes

Yes, because they have different slopes

No, because they have the same slope

No, because they have different slopes

Multiple Choice

Are the two lines shown parallel? Explain.

Yes, because they have the same slope.

Yes, because they have different slope.

No, because they have the same slope.

No, because they have different slopes.

Multiple Choice

Suppose a certain line has a slope of $\frac{2}{5}$ . What is the slope of the line that is perpendicular to it?

$\frac{2}{5}$

$-\frac{5}{2}$

$-\frac{2}{5}$

$\frac{5}{2}$

What is the length of AB?
What is the length of AD?

What is the length of BD?

How can I find the length of AB?

Is triangle XYZ a scalene, isosceles, or
equilateral triangle? How can we tell
(mathematically)?

Is triangle XYZ an acute, right, or obtuse
triangle? How can we tell?

Write this down! To determine if a triangle is acute, right, or obtuse when you know the side lengths:

If: it is a right triangle.

If: it is an acute triangle.

If: it is an obtuse triangle.

Multiple Choice

The vertices of $\Delta PQR$ are $P\left(4,1\right),\ Q\left(2,7\right),\ and\ R\left(8,5\right).$ Which of the following best describes the triangle?

acute and scalene

obtuse and scalene

acute and isosceles

right and isosceles

acute and equilateral
