It is: y = -1/5x+7 that is perpendicular to y = 5x+7
A triangular prism can have right angles. If the prism has two triangular ends, then each of the three 'sides' meets each of the ends at right angles.
It has right angles that are 90% when it meets or crosses.
They can but not always.
Complementary angles are 2 angles whose sum equals 90 degrees (a right angle).
A line is perpendicular if it meets at 90o.
Circle equation: x^2 +y^2 -8x +4y = 30 Tangent line equation: y = x+4 Centre of circle: (4, -2) Slope of radius: -1 Radius equation: y--2 = -1(x-4) => y = -x+2 Note that this proves that tangent of a circle is always at right angles to its radius
The tangent of a circle always meets the radius of a circle at right angles.
4 right angles, sides congruent, diagonals congruent
A pentagon can have anywhere from none to three right angles. For a pentagon to have any right angles however, it has to be uneven, because the sum of all interior angles of a pentagon always equals 540 degrees.

The answer has been right under your nose all this time.The equation of y equals -3x isy = -3x
It maens that JK meets LM at right angles of 90 degrees
