In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°
Answer:
√2 < 1.8
Step-by-step explanation:
Square of 2 is 1.41421356237309 and that is less than 1.8 continued.
The equation of the line containing the points (20,28) and (25,38) is
y = 2x ₋ 12.
Given the points are: (20,28) and (25,38)
First find the slope of the line passing through the given points.
we know that (x₁,y₁) and (x₂,y₂) is m = y₂ ₋ y₁/x₂ ₋ x₁
therefore the slope of line passing through the points (20,28) and (25,38) is:
m = 38 ₋ 28/25 ₋ 20
m = 10/5
m = 2
Consequently, the line's slope is 2.
Find the y-intercept now by using the slope and one of the two points.
y = mx ₊ b
28 = 2(20) ₊ b
28 = 40 ₊ b
28 ₋ 40 = b
b = ₋12
Next, represent the equation in slope-intercept form as follows:
y = mx ₊ b
y = 2x ₋ 12
hence the equation of the line is y = 2x ₋ 12.

Answer:
They are congruent.
Step-by-step explanation:
They both are the same shape and size. The side with one line is the same on the other. The side with two lines also matches the other triangle. Lastly, they both have an angle in the same place
