A triangle has side lengths of (2t + 2) centimeters, (6t – 7) centimeters,
Scorpion4ik [409]

A triangle is a three-sided polygon.  The sum of angles in a triangle is 180 degrees.

<em><u>Types of triangles </u></em>

  1. An equilateral triangle : the three sides are equal in length.
  2. An isosceles triangle : two sides are equal in length
  3. A right angled triangle : an angle measures 90 degrees

The perimeter of a triangle is (8t -7 + u) centimeters

The perimeter of a triangle is the sum of the three lengths of the triangle

2t +2 + 6t - 7 + u -2

Combine similar terms

(2t + 6t) + (2 - 7 - 2) + u

Add combined similar terms

8t -7 + u

PLEASE HELP&lt; ILL GIVE 45 POINTS AFTER YOU ANSWER!!!
Dima020 [189]

Given:

Vertices of △XYZ are X(-4,6), Y(6,1) and Z(1,1).

To find:

The vertices of ∆X′Y′Z′.

Solution:

According to the question, △XYZ is translated 3 units up to form the image ∆X′Y′Z′, so rule of translation is defined as

(x,y)\to (x,y+3)

Now,

X(-4,6)\to X'(-4,6+3)

X(-4,6)\to X'(-4,9)

Similarly,

Y(6,1)\to Y'(6,1+3)

Y(6,1)\to Y'(6,4)

and,

Z(1,1)\to Z'(1,1+3)

Z(1,1)\to Z'(1,4)

Therefore, X'=(-4,9),Y'=(6,4),Z'=(1,4).
