When you rotate the equilateral triangle 180 degrees will it look like a reflection?
Yes
What are reasons used in the proof that the equilateral triangle construction actually constructs an equilateral triangle triangle?
The following is the answer.
Which of the following could be the side measures of a right triangle?
There are no numbers on that list that could be the sides of a right triangle. Oh, all right. The following is the answer:
Which of the following may fall outside a triangle?
orthocenter and circumcenter
Why does a scalene triangle have no lines of symmetry?
The definition of the word "scalene" is a triangle having three sides of different lengths.The mathematical definition of "symmetry" is an exact reflection of form on opposite sides of a dividing line/plane.Therefore, by definition, no lines of symmetry exist in a scalene triangle.
what- One triangle shown is the preimage and the other triangle is the image.If R is the name of a point in the preimage, fill in the blank with the name of the image.image?
R'
Describe the difference between an image and a preimage?
A preimage is a transformed irritated or changed image. Such as a flipped triangle
Does an equilateral triangle have rotation or reflection symmetry?
reflective (aka reflection)
Suppose you want to reflect a triangle across the line y = x. Which of the following is the reflection matrix that you should use?
0, 1 1, 0
What is a triangle with one mirror line?
a reflection
How many lines of reflection does an equilateral triangle?
3
What are some real life examples of reflection?
Look in a mirror for an example of a reflection. Lift your right hand, and watch your left hand lift in the mirror, or so it appears!In geometry, reflection is a mirror image of a shape, etc.For example: the triangle b is the reflection of triangle a.▲ a▼ b
How many axes of reflection symmetry does an equilateral triangle have?
3
What kinds of symmetry do an equilateral and an isosceles triangle have?
An equilateral triangle has six symmetries, and an isosceles triangle has two. An isosceles triangle has a single axis of symmetry, the perpendicular bisector of the non-congruent side. This is a reflection symmetry. An equilateral triangle has rotational symmetry as well as reflection symmetry. It is invariant under rotations by 120 degrees.
Is the asosceles the reflection symmetry?
An isosceles triangle has 1 line of symmetry
Reflection of a triangle will change the measures of the interior angles by?
0 degrees
What shape has reflection symmetry but not rotations?
There are many. An isosceles triangle, for example.
