The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent.
The face opposite the apex is called the base. It is an optical element used to deviate light (towards the base of the prism). where i is the angle of incidence, iâ² the angle of emergence and a the prism angle (Fig. P15). See vergence adaptation; base setting; prism dioptre; prism power; minimum deviation of a prism; ophthalmic prism; recumbent spectacles; spectroscope. achromatic prism A prism that deviates light without dispersion.
