The first thing we will do is define an equilateral triangle:
In geometry, an equilateral triangle is a regular polygon with three equal sides. In traditional Euclidean geometry, equilateral triangles are also equiangular, that is, the three internal angles are also congruent to each other, each angle with a value of 60 °
Every equilateral triangle consists of three equal sides and three congruent angles.
Therefore, there can be a triangle with three equal sides (5 centimeters in this case).

Answer:
a) w = 8; y = 5.25
b) x = 10; z = 7.2
Step-by-step explanation:
a) Dimensions on the smaller figure are FA/F'A' = 3/4 times those on the larger figure.
6 = (3/4)w
w = 24/3 = 8
y = (3/4)·7 = 21/4 = 5.25

b) Dimensions on the smaller figure are ER/E'R' = 9/15 = 3/5 times those on the larger figure.
6 = (3/5)x
x = 30/3 = 10
z = (3/5)12 = 36/5 = 7.2
Answer:
Parallel - 8
Perpendicular - -1/8
Step-by-step explanation:
If a line is parallel to another then they have the same slope
If a line is perpendicular to another line then the slope is just flipped and so is the sign
Let's assume
length of rectangle is L
width of rectangle is W
the width of a rectangle is 3 meters more than one-fourth its length
so,

the perimeter is 10 meters more than twice its length
we know that
perimeter =2(L+W)
so, we get

now, we can simplify it

subtract both sides by 2L



now, we can find L

subtract both sides 3


multiply both sides by 4


so,
length of rectangle is 8 meter
width of rectangle is 5 meter ............Answer
