Shakira and Evelyn disagree on the method used to find the perimeter of an equilateral triangle whose side measures 4n-2. Whose

wel

Answer:

<h3>Both are correct</h3>

Step-by-step explanation:

All the sides of an equilateral triangle are equal. Hence;

Perimeter of an equilateral triangle = 3S

S is one of the side length

Given;

S = 4n-2

Perimeter of the triangle = 3(4n-2)

This can also be expressed as P = S + S + S

P = (4n-2) + (4n-2) + (4n-2)

This shows that both methods are correct

How to show opposite sides on a parallelogram are congruent

Marta_Voda [28]

Answer:

I am attaching a image to understand my proof.

Step-by-step explanation:

PROVE:-

AB = DC

AD = BC

∠ ABD = ∠ BDC (alternate angles are equal )

∠ DBC = ∠ ADB (alternate angles are equal )

∴ Δ ADB ≅ Δ CBD ( by ASA rule )

DC = BA ( corresponding sides of ≅ Δ )

AD = CB ( corresponding sides of ≅ Δ )

Hence it is proved that opposite sides of parallelogram are congruent )
