The slope of the line that passes through (x1,y1) and (x2,y2) is (y2-y1)/(x2-x1)
given
(p,a) and (p,-a)
slope=(-a-a)/(p-p)=-2a/0=undefined
means
the slope is undefined
x=something
(x,y)
(p,a)
x=p is the equation
the equation of a perpendicular line is y=k where k is any real number
the y intercept of y=k would be y=k or the pont (0,k)
A triangle is a polygon with three edges and three vertices, perimeter of ΔABC = 36cm.
<h3>Congruent triangles are what?</h3>
Congruent triangles are two triangles that are identical in terms of their size and shape. One of two congruent triangles remains congruent even if it is rotated, flipped, or turned. Two triangles must have the same sides in order for them to have the same angles and, as a result, to be congruent.
Triangles with equal measures are congruent.
36cm = perimeter of ΔABC
Here we have,
ΔABC ≅ Δ XYZ
So,

Therefore, perimeter of ΔABC = 36cm

Find the area of the triangle and the multiply by the depth of the solid.
Area = 1/2 x base x height
Area = 1/2 x 3 x 5
Area = 7.5 sq. ft.
Volume = 7.5 x 4 = 30 cubic ft.
