Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule
Ierofanga [76]

<em>Congruent triangles</em> are two or more triangles with the same length of <u>sides</u> and measure of internal <u>angles</u>. Thus the <em>required</em> proof is as shown below:

From the given diagram, it can be <u>observed</u> that:

AB = AC (<em>similar</em> property of two lines)

AC = AE (<u>similar </u>property of two lines)

Also,

m<A is a <u>common</u> angle to ΔABC and ΔADE

So that it can be <em>concluded </em>that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are <u>congruent</u>, then;

BC = DE (<u>corresponding</u> sides of <em>congruent</em> triangles)

Rectangle ABCD has vertices at A(-1,1), B(2,1), C(2,-5), and D(-1,-5). What is the perimeter of rectangle
Drupady [299]

Answer:

The perimeter of the rectangle is 18 units.

Step-by-step explanation:

The image included below presents the location of the points on the Cartesian plane. From Geometry we get that the perimeter (p), dimensionless, of the rectangle is the sum of its four sides. That is to say:

p = AB+BC+CD+DA (1)

Where AB, BC, CD and DA are the sides of the rectangle, dimensionless.

Each side value is found by means of the Pythagorean Theorem:

AB = \sqrt{[2-(-1)]^{2}+(1-1)^{2}}

AB = 3

BC = \sqrt{(2-2)^{2}+[(-5)-1]^{2}}

BC = 6

CD = \sqrt{(-1-2)^{2}+(5-5)^{2}}

CD = 3

DA = \sqrt{(-1-1)^{2}+[1-(-5)]^{2}}

DA = 6

And the perimeter of the rectangle is:

p = 3+6+3+6

p = 18

The perimeter of the rectangle is 18 units.
