The
purple line is tangent. Tangent line intersects a circle in only 1 point
The
yellow dot is the point of tangency. It is the point where tangent line touches the circle
The
light blue line is secant. Secant line intersects a circle in 2 points
The
red line is the radius. Radius is the distance from center to the outer rim of the circle.
The
green line is the diameter. It is the line passing through the center of a circle. It measures twice the radius
The
gray line is the chord. Chord is the line whose endpoints lie on the circle.
Arc AB is a minor arc
Arc ABCD is a major arc

Hope this helps :))
Two lines are perpendicular if and only if the product of their slopes is - 1.
So, you just need to find the slope of each line and find out the product of their slopes.
I will do one example for you.
L1: y = 3x + 5
L2: y = - 3x + 14
L3: y = -x/3 + 14
The slope of a line is the coefficient of the x.
So the slopes are:
L1: slope 3
L2: slope -3
L3: slope -1/3
So now multiply the slopes of each pair of lines:
L1 and L2: 3 * (-3) = - 9 => No, they are not perpendicular
L2 and L3: (-3) * (-1/3) = 1 => No, they are not perpendicular
L1 and L3: (3) * (-1/3) = -1 => Yes, they are penpendicular.
