### Math review for Test

Question | Answer |
---|---|

What is the measurement of the exterior angle in the diagram? Look at Image 1. | A:95 X=10 |

What series of transformation could have been used? Look at Image 2. | A: Rotate 180 degrees OR Reflect over Y then Reflect over X OR Reverse the Two |

What is the relationship Between 68 and angle 4 and angle 5? Look at Image 3. | A:68, 4, and 5=180 |

If angle 4 is 75 what must be the measure of angle 3? Look at Image 3. | A:Angle3=105 |

Find the measure of angle 5. Look at Image 3. | A:Angle 5=37 |

Andrew constructed a triangle so that the measurement of angle1 and angle2 were congruent. If angle 3 measure 50 degrees, what is the measurement of angle 1? | A:X=65 |

Triangle 1 and Triangle 2 are similar why? Look at Image 4. | A:AngleC=26 AngleH=64 |

Triangle RST is the result of a sequence of transformations using the pre- image Triangle ABC. If the first transformation of the sequence was dilation about the origin, identify the scale factor. Look at Image 5. | A:2 |

Using Image 6 find BE. | A:X=4.5 |

In the Image 7, Lines A and B are parallel. | A:X=59 |

The angle measures of a triangle are 2x+3 degrees, 4X+2 degrees, and 2X-1 degrees. Find x and find the measure of eac angle of the triangle? | A:X=22 Measures:47,90,43 |

Which of the transformations would NOT preserve size and shape? | A:Dilations |

A triangle has vertices of A(-3,4),B(1,1), and C(2,3). Find the coordinates of the triangle if it is reflected over the Y-axis , and then dilated by a scale factor of 2. | A:A. A'(3,4) B'(-1,1) C'(-2,3) B. A''(6,8) B''(-2,2) C''(-4,6) |

Find The coordinates if the original triangle A(-3,4),B(1,1), and C(2,3) is dilated by a scale factor of 2 and then reflected over the y-axis. | A:A. A'(-6,8) B'(2,2) C'(4,6) B. A''(6,8) B''(-2,2) C''(-4,6) |

Identify the angel pair created in Image 8. | A: Alternate Interior Angle |

Find the value of X in Image 8. | A:X=12 |

What is the measurement of A? Look at Image 9. | A:A=105 |

Solve for X. Look at Image 9. | A:X=15 |

What is the measurement of Y? Look at Image 9. | A:Y=75 |

What is the measurement of X? Look at Image 10. | A:X=50 |

What is the measurement of Y? Look at Image 10. | A:Y=100 |
