Ants, tangents, and angle measuressecant:theorem 10.12 if two secants of chords intersect in the interior of the circle, then the measure of an angle formed is one half of the sum of the measure of the arcs inter. ngle. find x in the following:qrs, ifif two secants, a secant and a tangent, or two tangents intersect in the exterior of a circle.
Secants Tangents And Angle Measures Worksheets Answers The formula. the angle formed by the intersection of 2 tangents, 2 secants or 1 tangent and 1 secant outside the circle equals half the difference of the intercepted arcs! therefore to find this angle (angle k in the examples below), all that you have to do is take the far intercepted arc and near the smaller intercepted arc and then divide. Formed by a tangent and a secant, and an angle formed by two secants. just like an angle inside or on a circle, an angle outside a circle has a specific formula, involving the intercepted arcs. investigation 9 8: find the measure of an angle outside a circle tools needed: pencil, paper, ruler, compass, protractor, colored pencils (optional) 5.

When tangents intersect outside a circle, the measure of the angle they form is one half the difference of the intercepted arcs. since the tangents are at the endpoints of the same diameter, both intercepted arcs would have to measure 180 degrees. this means the angle would have a measure of one half times the difference of 180 and 180, which is 0. 40∘ = 1 2(140∘ − x) 40 ∘ = 1 2 (140 ∘ − x) then. 80∘ = 140∘ − x 80 ∘ = 140 ∘ − x. so that. x =60∘ x = 60 ∘. it’s that simple. sometimes the far arc and near arc are a little more difficult to determine, as you will see in the next example, but the procedure is the same. example: find the measure of the arc or angle.
