Are The Bases Of An Isosceles Trapezoid Congruent? Now, if a trapezoid is isosceles, then the legs are congruent, and each pair of base angles are congruent. In other words, the lower base angles are congruent, and the upper base angles are also congruent. Does an isosceles trapezoid have congruent diagonals? Isosceles trapezoids also have
Which Two Angles Are Equal In An Isosceles Triangle? Every isosceles triangle has an axis of symmetry along the perpendicular bisector of its base. The two angles opposite the legs are equal and are always acute, so the classification of the triangle as acute, right, or obtuse depends only on the angle between its two
Is Altitude Always 90 Degree? Perpendiculars are lines that form 90° angles when they meet. Altitudes are segments that are perpendicular to a side of a triangle and reach from that side to the opposite corner of the triangle. Does altitude make 90 degrees? When the star is directly overhead at zenith, that angle is
