Points, Lines, Segments, & Planes
What is a point in Geometry?
A location on the plane.
What is ASA (Angle-Side-Angle) postulate in Triangle Congruence?
The ASA postulate is when two angles and the side included between them of one triangle are equal to the two corresponding angles and the side included between them of another triangle, the two triangles are congruent.
An Equilateral Triangle is . . .
A triangle where all three sides are equal in length.
What is a Rotation in Geometry Translations?
A Rotation in Translations occurs when each point in a figure and rotates it a certain number of degrees around a given point.
What is an interior angle?
An angle that has its vertex at the intersection of two lines that intersect inside a circle.
A line consisting of two or more points is a . . .
A line segment
What is the SSS (Side-Side-Side) postulate in Triangle Congruence?
The SSS postulate is when the three sides of one triangle are equal to the three corresponding sides of another triangle, the two triangles are congruent.
An Obtuse Triangle . . .
has one of its interior angles measure to more than 90° degrees.
What is a Translation in Geometry Translations?
When each point in a figure and slides it the same distance in the same direction.
An angle whose vertex is outside a circle, and the sides of the angle are secants or tangents of the circle is a
. . .
Exterior Angle
Two lines that meet in a point are called . . .
Intersecting Lines.
What is SAS (Side-Angle-Side) postulate in Triangle Congruence?
The Side-Angle-Side postulate is when two sides and an included angle of one triangle are congruent to two corresponding sides and an included angle of another triangle, then the triangles are congruent.
An Isosceles triangle is a . . .
Triangle that only has two sides of equal length.
What is a Reflection in Geometry Translations?
A mirror image of a given shape, & every point in a/the figure is at equidistant from each corresponding point in another figure.
What is and Arc & Chord?
An Arc is a part of a circle's circumference & is parallel to each other, then two arcs between are congruent. A Chord is a straight line with both endpoints on the circle.
A plane in Geometry is a . . .
Flat surface that extends infinitely in all directions.
Whet is the AAS (Angle-Angle-Side) postulate in Triangle Congruence?
The AAS postulate is when the two angles and non-included sides of one triangle are congruent to two angles and a non-included side of another triangle, then the triangles are congruent.
An Acute Angle has . . .
All three internal angles that measure up to less than 90 degrees.
What is Dilation in Geometry Translations?
Dilation is a transformation, that is used to resize the object.
What is a central angle?
A circle whose vertex is the center of a circle and sides are radii intersecting the circle in two distinct points A & B.
A line of points that extends infinitely in both directions is called a . . .
Line
What is the RHS (Right angle-Hypotenuse-Side) postulate in Triangle Congruence?
When the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.
A Scalene Triangle is a . . .
Triangle where all sides are unequal sides.
The definition of transformations is . . .
To change.
What is the formula for finding the arc length of a circle?
S (arc length) = r (radius) 0 (Angle in radians)
