A ____________ angle is one that measures 90 degrees. 

A RIGHT angle is one that measures 90 degrees.

Classify this triangle according to its side lengths. 

Isosceles Triangle (2 congruent sides) 

100

State the most specific name for this figure. 

Parallelogram -- it has two pairs of parallel sides

What is the area of the rectangle? Use standard "units" for your unit. 

24 square units

200

Describe and define this figure. Name it using the appropriate symbol. 

Ray, a straight path that has one endpoint and goes forever in one direction. 

Named starting with the end point and has a mini-ray overhead. 


200

Draw a 35 degree angle using a protractor.

An equilateral triangle has ________ sides that are equal in length. What are the measure of its angles? 

An equilateral triangle has 3 equal sides and 3 equal angles. The sum of the angles in a triangle is 180, if the side lengths are equal, the angles that they form must also be equal, so 180/3=60 degrees. 

200

State the most specific name for this figure. 

Kite -- two pairs of adjacent, congruent (same size) sides

Find the perimeter of the shape below. 

7+7+3+3 = 20 units

Name a ray on this figure. Use a symbol to write the name. 

Ray BA or Ray DE (symbol is arrow above the name).

Stephen says that the measure of this angle is 60 degrees. Lucas says that it is 120 degrees. Who is correct and why? 

Part B Classify the angle as acute, right or obtuse. 


Lucas is correct. It is an obtuse angle , one that is larger than 90, smaller than 180.

300

Is it possible to have a triangle that is a right, isosceles triangle? If no, explain. If yes, sketch and explain. 

Yes! You can have one right angle and two sides of equal length. See below... For an extra 50 points, tell the measure of the other two angles. 

300

State all possible names for this figure: 

Polygon, quadrilateral, parallelogram, rectangle, rhombus, square 

300

Find teh perimeter of the shape below: 

It is a regular pentagon, so 3+3+3+3+3=15 or 3x5 =15 

15 units 

400

Name all the figures that were used to construct this letter. 


Line OQ, Line RT, Line PS

Find the measure of the angle marked x. 

A straight line measures 180 degrees. 180-118=62. The angle marked x measures 62 degrees. 

400

Classify the triangle. Use one side name and one angle name. 

Right Triangle (one 90 degree angle) 

Scalene Triangle (no sides are equal in length)

400

Is this rhombus a rectangle? Explain. 

A rhombus is not a rectangle. Both shapes are parallelograms, but in order to be a rectangle, the shape has to have four right angles. Therefore it would be a square!

5PP is making a garden on the back patio. It will be a 5ft x 9ft rectangle. We need to buy fencing for our garden to keep out animals. The fence costs $12 per foot. How many feet do we need to fence in the entire garden and how much will it cost? 


5 +5+9+9= 28 ft 

28 x 12 = $336

Classify this angle, and estimate its measure. 

It is a reflex angle and seems to be about 270 degrees.

Find the missing angle. 


The sum of the angles in a triangle is 180 degrees. 85+50=135. 180-135= 45 degrees.
