First plot all points as shown in attachment and draw the triangles ABC, XYZ, MNO, JKL and PQR

Now we will do following steps on triangle MNO

(1) Relect it about x axis as shown in second attachment by triangle M'N'O'

(2) Reflect triangle M'N'O' about y axis as shown by triangle M"N"O"

(3) Now translate this triangle M"N"O" as shown by M"'N"'O"'

Since traingle M"'N"'O"' overlaps triangle ABC exactly, so it proves that triangle MNO is congruent to triangle ABC

So triangle MNO can be proved congruent to triangle ABC by sequence of reflection and translation

---------------------------------------------------------------------------------------------------------------

Now can see in third attachment that triangle PQR can be rotated about point Q 90° anticlockwise direction as shown to get triangle P'Q'R' which will exactly overlap triangle JKL. So triangle PQR can be proved congruent to triangle JKL by single rotation.

[HELP FAST] A line passes through the point (4, -9) and has a slope of -5/4
DENIUS [597]

Answer:

y= \frac{-5}{4}x -4

Step-by-step explanation:

using pt-slope form, we get  y - (-9) = \frac{-5}{4}(x-4). Using the Distributive Property and Addition Propert of Equality, we can simplify this equation into y = \frac{-5}{4}x + 5 by factoring -5/4 into (x-4) and subtracting 9 from both sides.

Consider isosceles ΔXYZ.
Rom4ik [11]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The length of the legs XY and YZ is equal to 39 units.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°. An isosceles triangle has two sides out of three equal.

A.) The value of n can be found by equating XY and XZ together,

XY = XZ

9n + 12 = 15n - 6

12 + 6 = 15n - 9n

18 = 6n

n = 3

Hence, the value of n is 3.

The length of different legs of the triangle is,

B.) XY = 9n + 12 = 9(3) + 12 = 27 + 12 = 39

C.) YZ = 15n - 6 = 15(3) - 6 = 45 - 6 = 39

Hence, the length of the legs XY and YZ is equal to 39 units.

Korvikt [17]

Answer:

hey,its option a

Step-by-step explanation:

because angle F= angle M and angle G= angle L

and angle H= angle N

To know third angle in ∆HGF

,we know sum of all angles in a triangle is 180°

______________________________

let angle H be unknown value x

x+51+36=180

x=180-87 ---------------- 1

similarly in ∆MNL

let angle be y

51+36+y=180

y=180-87----------------2

_______________________________

From 1&2 we observe qngle x= angle y
