Determine which of the lines, if any, are parallel. Explain.
amid [387]

Answer:

Line A and Line C are parallel

Step-by-step explanation:

<u>Slope Equation: </u> m=\frac{y_{2} - y_{1}}{x_{2} - x_{1}}

<u>Step 1:  Find the slope of the first line</u>

Line a passes through (-1, -2) and (1, 0).

m = \frac{(0- (-2))}{(1 - (-1))}

m=\frac{2}{2}

m=1

<u>Step 2:  Find the slope of the second line</u>

Line b passes through (4, 2) and (2, -2).

m = \frac{(-2- 2)}{(2 - 4)}

m = \frac{-4}{-2}

m=2

<u>Step 3:  Find the slope of the third line.</u>

Line c passes through (0, 2) and (-1, 1).

m=\frac{(1-2)}{(-1 - 0)}

m=\frac{-1}{-1}

m=1

Answer:  Line A and Line C are parallel

A four-sided shape has four congruent angles and sides. Which quadrilateral could it be? A. quadrilateral B. trapezoid C. square
Gnoma [55]

Answer:

C. square

Step-by-step explanation:

<u>Congruent</u> means "the same" (having the same shape and size).

Any four-sided, 2-dimensional shape with straight sides is called a <u>quadrilateral</u>.

There are 6 special types of quadrilaterals:

<u>Rectangle</u>

  • Opposite sides are parallel and equal in length
  • All interior angles are 90°

<u>Square</u>

  • All sides are equal in length
  • All interior angles are 90°

<u>Rhombus</u>

  • All sides are equal in length
  • Opposite sides are parallel
  • Opposite angles are equal

<u>Parallelogram</u>

  • Opposite sides parallel and equal in length
  • Opposite angles are equal

<u>Trapezoid</u>

  • One pair of opposite parallel sides

<u>Isosceles Trapezoid</u>

  • One pair of opposite parallel sides
  • One pair of non-parallel sides equal in length
  • Two pairs of equal base angles

<u>Kite</u>

  • Two pairs of adjacent sides equal in length
  • The angles included between the sides of differing lengths are equal

<u>Conclusion</u>

A four-sided shape that has four congruent angles and sides is a SQUARE.

Estimate the product of<br> 5<br> and 4<br> Then find the product.
Nana76 [90]

1: Look at the 4, its a lot easier to multiply 5 x 5 rather than 5 x 4, plus if you are estimating, you are going to round either up or down.

2: Multiply 5 x 5 // the answer is 25.

3: Multiply 5 x 4 (the original) // which is 20.
