Base angles theorem. The base angles theorem states that if the sides of a triangle are congruent (Isosceles triangle)then the angles opposite these sides are congruent. Start with the following isosceles triangle. The two equal sides are shown with one red mark and the angles opposites to these sides are also shown in red.

from 1821 and Cauchy's theorem on power series expansions of complex. valued functions nite objects had no material base and therefore could not be perceived by of contact' exists depends on which definition of an angle we use.

If two sides of a triangle are congruent, then the angles opposite of those sides are congruent. If two The altitude to the base of an isosceles triangle bisects the vertex angle. 4. The altitude to the base of an isosceles triangle bisects the base. The following diagram shows the Isosceles Triangle Theorem.

If ∠S = 60 0 then find the remaining angles. Solution : PQ||RS and PS = QR, so trapezoid PQRS is an isosceles trapezoid. In isosceles trapezoid, base angles are equal.(trapezoid and its theorems) ∠S = ∠R and ∠P = ∠Q But ∠S = 60 0 ∴ ∠R = 60 0 Let ∠P = ∠Q = x Sum of all the angles in a quadrilateral is 360.
