What are the end points of the triangle called? How are they labeled?
horrorfan [7]

For this case we have that by definition:

A triangle is defined by three lines that are called sides, or by three points called vertices.

We know that:

  1. <em>The vertices of a triangle are labeled with capital letters. </em>
  2. <em>The sides of a triangle are written with lowercase letters. </em>
  3. <em>The angles of a triangle are written similarly to the vertices. </em>

Answer:

The end points of the triangle are called vertices.

They are labeled in capital letters.

Write the equation of the line that passes through (3, 4) and (2, −1) in slope-intercept form.
3241004551 [841]
(3,4)(2,-1)
slope(m) = (y2 - y1) / (x2 - x1)
slope(m) = (-1-4) / (2 - 3) = -5/-1 = 5

y = mx + b
slope(m) = 5
u can use either of ur points...(3,4)...x = 3 and y = 4
now we sub and find b, the y int
4 = 5(3) + b
4 = 15 + b
4 - 15 = b
- 11 = b

so ur equation is : y = 5x - 11 <===
