An octagon has 8 sides. Each side is given as 2a + 1

Perimeter = 8(2a + 1)

= 16a + 8

Answer: 16a + 8

as we all know ... an octagon has 8 corners / sides

and they told that each side is equal to 2a + 1

so we need to make an equation which will be <u>8 (2a+1) </u>

ans now we need to<em> multiply 8 with both 2a and 1 </em>

so, 8 ( 2a + 1 )

16a + 8

we cant do this further as its not "like"

so the answer is<em><u> 16a + 8 </u></em>

Given ∆ABC with vertices A(−4, −3), B(0, 0), C(2, −3) and ∆DEF with vertices D(3, 1), E(6, -3), F(3, −5), use the definition of
dimaraw [331]

By SSS congruency criteria ΔABC ≅ ΔDEF

<h3>What is congruency?</h3>

Two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

The given vertices of the triangles are;

ΔABC: A(−4, −3), B(0, 0), C(2, −3)

ΔDEF:  D(3, 1), E(6, -3), F(3, −5)

The lengths of the sides of ΔABC are

AB = √((0+4)² + (0+3)²) = √25 = 5

BC = √((2-0)² + (-3 - 0)²) = √13  

AC = √((2+4)² + (-3 +3)²) = √36 = 6

The lengths of the sides of ΔDEF are;

DE = √25=5

EF = √13

DF = √36 = 6

As,

AB= DE, BC = EF , AC= DF

So, By SSS congruency criteria ΔABC ≅ ΔDEF
