Transformations
what is transformation?
The movement of a figure in a plane from its original position, the pre-image, to a new position, the image.
what is the formula for Pythagorean theorem?
a2+B2=c2
A right triangle has an angle that measures 56 degrees. What is the measurement of the third angle?
34 degrees
This is the geometry word that means that two images are equal or have the same measurement OR that they are the SAME SIZE and the SAME SHAPE.
congruent
what is Pre-image?
A shape that undergoes a transformation.
which side is always the longest?
C2
A triangle has angles that measure 72 degrees, 23 degrees and x + 25 degrees. THIS is the value of x.
60 degrees
Angle J sits outside an extended line of Triangle FGH. Angle J is called THIS kind of angle.
exterior angle
what is Similar figures?
figures that have the same shape, but not necessarily the same size; The sides of the corresponding sides are proportional or all the angles are equal.
what is the longest side called?
the hypotenuse
Construct Triangle GHI with an EXTERIOR angle extended from Angle G. What are the names of the two remote interior angles?
angles H and I
Angle F and Angle G sit within two parallel lines on opposite sides of a transversal. This is the term that describes the relationship between Angles F and G.
alternate interior angles
what is scale factor?
The size change from the pre-image to the image
what is the measurement of a right triangle?
90 degrees
An isosceles triangle has two angles that measure 74 degrees. THIS is the measure of the third angle.
32 degrees
This is the term for a straight line that crosses two parallel lines.
transversal
what does translation mean?
to slide
who created the Pythagorean theorem?
the Greek mathematician and philosopher, Pythagoras.
Triangle JKL has an exterior angle that sits beside Angle L and measures 86 degrees. Angle J measures 37 degrees. THIS is the measurement of angle K.
49 degrees
This is a geometry term that describes two angles that sit in the same position, but on two different parallel lines.
corresponding angles
