Q1
This term is an exact location in space and has no size or dimension
What is a point?
This segment connects a vertex to the midpoint of the opposite side of a triangle
What is a median?
This is the distance from the center of a circle to any point on the circle.
What is the radius?
A segment with both endpoints on a circle is called this.
What is a chord?
A straight path that extends infinitely in both directions and contains infinite points
What is a line?
This point is where all three medians of a triangle intersect.
What is the centroid?
An angle whose vertex is at the center of a circle is called this.
What is a central angle?
A line that intersects a circle at exactly one point is called this
What is a tangent?
A flat surface that extends infinitely in all directions and is made up of infinitely many lines
What is a plane?
In triangle ABC, DE connects the midpoints of two sides. If BC = 16, find DE
What is 8?
A central angle measures 80°. Find the measure of its intercepted arc.
What is 80°?
If two chords intersect inside a circle, the products of their segment lengths have this relationship.
What is they are equal?
When two lines meet, this is what they do.
What is intersect?
The vertices of a triangle are A(3,3), B(9,3), and C(6,9). Find the centroid
What is (6,5)?
An inscribed angle intercepts an arc measuring 120°. Find the angle measure
What is 60°?
Two chords intersect inside a circle. One chord is split into segments of lengths 2 and 9. The other chord is split into segments of lengths 3 and x. Find x.
What is 6?
This uses a compass and straightedge to copy a line segment or create congruent lengths.
What is a geometric construction?
In triangle ABC, AB = 8 and AC = 12. An angle bisector from A meets BC at D. If BD = x and DC = 9, find x.
What is 6?
Two arcs measure (3x + 10)° and (5x − 30)°. If they are equal, solve for x.
What is 20?
From a point outside a circle, a tangent of length 10 and a secant are drawn. The external part of the secant is 5, and the inside segment is x. Find x.
What is 15?
