Question

in the figure tangents at B amd C at the circle with center O intersect at point A. if angle BAC = 90°.​

Answer 1

Answer:

Step-by-step explanation:

Ab equals to AC because tangents on the same.

angle BAC is equal to 90 degree given Angle B and angle C is equal to 90° because tangent perpendicular to radius

ab equals to AC because radii of a same circle

angle is equal to 90 degree by angle sum property

therefore a quadrilateral with all angles is equal to 90 degree and two pairs of adjacent sides equal is a square
