Basic Triangle Geometry
This is any angle that is less than 90 degrees.
Acute
Two straight lines that intersect at a 90 degree angle
Perpendicular
This country has the most coastline of any in the world eh.
Canada
42 + 32
5 * 4 + 3 - 52
-2
This is any angle that is more than 90 degrees
Obtuse
Two angles of a triangle are:
30 degrees
60 degrees
The third angle is this.
Right
That's the 6th planet in our solar system.
SATURN
54 / 52
25
4(3 + 8) - 2 * 9
26
This type of triangle has two legs that are the same length.
Isosceles
These two straight lines will never intersect.
Parallel.
The letter T and an island have this is common
They are both in the middle of water
73 * 75
78
6 * 4 / 12 + 72 / 9 - 9
2
This type of triangle has all 3 sides the same length.
Equilateral
That's the Pythagorean Theorem.
a2 + b2 = c2
We see it once in a year, twice in a week, and never in a month.
The letter e.
(x+1)2
x2 + 2x + 1
32 / 3 + 2(9 + 10) - 8 + 4 * 3
45
That's what all the interior angles of a triangle add up to.
180 degrees
That's the sin of 30 degrees
1/2
This gets bigger the more you take away
Hole
(52 * 53) / 54 (23 - 32)
-5
52 - (22 * 5) / 2 + 22(3 - 23)
-5
