If the four pairs of intersecting lines have opposite reciprocal slopes, they have 90 degree angles. If the distance of all the sides are the same, it’s a square.

Sse the distance formula to find the length of the sides... opposite sides equal it could be a rectangle or parallelogram all sides equal, square or rhombus adjacent equal, kite and then the slope is used to check angles if the product of the 2 lines in -1 the lines are perpendicular (right angle) the the slopes of 2 lines are the same the sides are parallel. hope it helps.

A Triangle has an area of 36cm^2. The base and height are scaled by a factor of 5. What is the area of the resulting triangle?

Finger [1]

Answer:

Area of resulting triangle will be 900 $cm^2$ .

Step-by-step explanation:

When sides of any polygon if scaled by a factor of k

then area is scaled by $k^2$

According to the above statement

therefore here in the question since area of original triangle was 36 $cm^2$

and both base and height are scaled by a factor of 5.

therefore area of scaled triangle will be $5^2$ times of the original

that is 25 x 36 which gives 900 $cm^2$

So area of resulting triangle will be 900 $cm^2$

What are the equivalent fractions for 2 1/5 and 1 5/6 using 30 as the common denominator

Anuta_ua [19.1K]

Answer:

2 6/30 and 1 25/30

Step-by-step explanation:

First, you need to find 30÷5 and 30÷6. You do this because you need to know the multiplier when you create an equivalent fraction. 30÷5 is 6 and 30÷6 is 5. 2 1/5. You need to multiply the 1 and 5 by 6, that is 2 6/30. 1 5/6. 5 and 6 multiplied by 5 is 25 and 30. 1 5/6=1 25/30

In triangle ACD, what is the value of X: who ever show works gets brainly.

Keith_Richards [23]

Answer:

x = 7.5

Step-by-step explanation:

Given that BE is parallel to CD and intersects the 2 other sides, then it divides the 2 sides in proportion, that is

$\frac{AB}{BC}$ = $\frac{AE}{ED}$ , substitute values
