what is segment segment?
a part of a figure cut off by a line or plane intersecting it, in particular.

which of the following cannot be used to prove that two triangles are congruent?
AAA congruence postulate

why are circles similar?
Theorem: Any two circles are similar. Proof: Given a circle of radius r and a second circle of radius R , perform a translation so that their centers coincide. points of one circle and maps them onto the second. The value of pi is the same for all circles.

what is scale factor?
A scale factor is a number which scales, or multiplies, some quantity.

8. Which of the following is / are true? 1. A triangle is congruent to itself 2. An isoceles triangle has two congruent correspondances 3. An equilateral triangle has six congruent correspondances
all are true

what is a chord?
a straight line joining the ends of an arc.

what is the similarity?
Image result for similarity geometry definition In geometry two triangles, and , are similar if and only if corresponding angles are congruent and the lengths of corresponding sides are proportional

In Ms. McLean's class, the students pick unique numbers from a hat to decide the order in which they will present their group projects. Yoshi picks a number first, and Andrew picks second. Are these two events dependent or independent?
dependent

explain why vertical angles are congruent
when two lines intersect to make an "x", angles on opposite sides of the "x" are called vertical angles. These angles are equal.

Choose the correct choice based on the statements given. (1) The leg AB of triangle ABC is equal to the leg DE of triangle DEF. (2) The leg BC of triangle ABC is equal to the leg EF of the triangle DEF.
BOTH statements (1) and (2) TOGETHER are sufficient, but NEITHER statement ALONE is sufficient

what is a circumscribed angle?
A circumscribed angle is an angle whose rays are tangent to the circle.

what is similarity transformation ?
A similarity transformation is a conformal mapping whose transformation matrix can be written in the form.

what is an interior angle
the angle between adjacent sides of a rectilinear figure.

what is a tagent line?
In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point.
400
what is congruence ?
Exactly equal in size and shape. Congruent sides or segments have the exact same length. Congruent angles have the exact same measure. For any set of congruent geometric figures, corresponding sides, angles, faces, etc. are congruent.

what are congruent diagonals?
A square is a parallelogram with four congruent sides and four right angles. A quadrilateral is a square if and only if it is a rhombus and a rectangle. Proof of Theorem: If a parallelogram is a rhombus, then the diagonals are perpendicular.

Is "angle-angle-angle", a valid rule for proving triangles congruent?
no

define the radian measure of angle
Image result for the radian measure of angle definition The radian measure of a central angle of a circle is defined as the ratio of the length of the arc the angle subtends, s, divided by the radius of the circle, r.
