wh
A = ℓw
b
A = ½bh
r
A = πr²   C = 2πr
abc
a² + b² = c²
Altitude-to-hypotenuse (right triangle):
altitude² = (segment 1)×(segment 2)
leg² = (adjacent segment)×(hypotenuse)
leg1 × leg2 = hypotenuse × altitude

Similar triangles: corresponding angles equal; corresponding sides proportional.
Congruent triangles: SSS, SAS, ASA, AAS.
Sum of interior angles of a triangle = 180°.
