The lower chassis of BLOODHOUND SSC uses the particular quality of triangles resulting in a strong yet light construction.
Triangles have three sides of various lengths and three internal angles. We measure these angles in degrees.
The measure of the total internal degrees of a triangle equals 180°. Knowing this allows us to tackle the following mathematical classic:
The Great Pyramid
In the following diagram of the front view of the Great Pyramid:
• The measure of the angle PRQ is 120 degrees.
• The measure of the angle PST is 110 degrees.
Q. What is the measure of the angle RPS in degrees?
Angles on a straight line add up to 180 degrees.
So, angle PRS = 180 degrees - angle PRQ = 180 - 120 degrees = 60 degrees
and, angle PSR = 180 degrees - angle PST = 180 -110 degrees = 70 degrees
The angles in a triangle add up to 180 degrees.
So angle RPS + angle PRS + angle PSR = 180 degrees
therefore angle RPS = 180 degrees - angle PRS - angle PSR = 180 - 60 - 70 degrees = 50 degrees
