Geo EOC Review (Name That Formula/Property #2)

The sum of the measures of the interior angles of a triangle is 180 degrees.

The Pythagorean Theorem (a² + b² = c²)

Two chords are congruent if they are equidistant from the center of a circle.

The measure of an inscribed angle is 1/2 the measure of its intercepted arc.

The sum of the measures of the interior angles of a triangle is 180 degrees.

The measure of a central angle is equal to the measure of its intercepted arc.

A minor arc is an arc whose measure is less than 180 degrees.

The measure of an inscribed angle is 1/2 the measure of its intercepted arc.

If two chords intersect inside of a circle, the product of the two parts of one chord will be equal to the product of the two parts of the other chord.

The measure of the angle formed by the two intersecting chords is equal to ½ the sum of the measures of the intercepted arcs.

If a line is tangent to a circle, then it is perpendicular to the radius drawn to the point of tangency.

If two segments from the same exterior point are tangent to a circle, then they are congruent.

If a quadrilateral is inscribed in a circle, then opposite angles are supplementary.

If a quadrilateral is inscribed in a circle, then opposite angles are congruent.

If an angle is inscribed in a semi-circle, then it is a right angle.

None of the above.

A = (90/360) (2𝜋r)

A = (90/360) (𝜋r2)

C = 2𝜋r

V = Bh

Opposites are congruent.

Opposite sides are parallel.

Opposite angles are congruent.

Consecutive angles are supplementary.

4/x = 18/22

4/22 = x/x+22

x/4 = 22/18

x/22 = 18/4

sin(27)=𝑥/15

cos(63) = 𝑦/15

tan(27) = y/x

sin(63)=𝑥/15

Tan 28 = Opp/adj

Sin 28 = opp/hyp

Cos 28 = adj/hyp

Tan 28 = adj/opp
