Mand n are the acute angles of an isosceles right triangle. select the true statements. cosm = sinm cosm = cosn cosm = tann sinn = cosm tanm = tann

An isosceles triangle has two sides equal. Since it's also a right triangle , the angles will be 90°, 45°, 45°.
M = 45°
N = 45°

cos(45°) = sin(45°)
true

tan(45°) = tan(45°)
true
cos(45°) = cos(45°)
true

cos(45°) = tan(45°)
false

sin(45°) = cos(45°)
true
