Consider the diagram.
Radda [10]

The congruence theorem that proves that △LON ≅ △LMN is: A. SSS congruence theorem

<h3>What is the SSS Congruence Theorem?</h3>

According to the SSS congruence theorem, if all three corresponding sides of two triangles are congruent, then both triangles are congruent.

In the image given, we have:

  • ON ≅ MN
  • LO ≅ LM
  • LN ≅ LN (reflexive property)

This means all three corresponding sides are congruent, therefore, the congruence theorem that proves both triangles are congruent is:

A. SSS.

Find the distance between two points ( -1,1) and (2,-4)
sladkih [1.3K]

Answer:

The distance between two points ( -1,1) and (2,-4) is:

d=\sqrt{34}  or d = 5.8 units.

Step-by-step explanation:

Given the points

  • (-1, 1)
  • (2, -4)

Finding the distance between (-1, 1) and (2, -4) using the formula

d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}

substitute (x₁, y₁) =  (-1, 1)   and  (x₂, y₂) = (2, -4)

   =\sqrt{\left(2-\left(-1\right)\right)^2+\left(-4-1\right)^2}

   =\sqrt{\left(2+1\right)^2+\left(-4-1\right)^2}

   =\sqrt{3^2+5^2}

   =\sqrt{9+25}

   =\sqrt{34}  units

or

d = 5.8 units

Therefore, the distance between two points ( -1,1) and (2,-4) is:

d=\sqrt{34}  or d = 5.8 units.
