Question: 300 points

In a triangle, we all know that midpoint is the center point of the line segment. How about if it is connected with another line segment from the opposite vertex, what do we call it?

Answer: 300 points

Median

Question: 400 points

I know that you are assuming that the next answer is angle bisector but you’re unfortunately wrong. =,) Now, Can you tell me it’s definition.

Answer: 400 points

Well….

It is a line segment that divides the angle into two congruent measures.

Question: 500 points

If altitude, median and angle bisector are the other three line segments found inside the triangle, what do you mean those three line segments that form a shape of triangle?

Answer: 500 points

Sides

Question: 100 points

If the square paper is diagonally cut, we have 2 separate triangles. What is its classification in terms of sides?

Answer: 100 points

So, it’s FALSE….

Question: 400 points

Is it possible that all triangles have hypotenuse? Support your answer.

Answer: 400 points

NO! because among the classifications of triangles, only the right triangle has 90º as one of the angle measures.

Question: 500 points

The other parts of the quadrilateral are bases, base angles, and legs. Now, what is the comparison between bases and legs?

Answer: 300 points

Bases are parallel sides while legs are non-parallel sides.

Question: 400 points

Assuming that you bake a cake in quadrilateral shape. You put the first topping letter H on the first corner, K consecutively on the second corner, L on the next corner, and lastly M respectively. How many diagonal(s) can be formed and what are those line segments?

Your rectangular garden has an area of 150 sq. m. You want to put fence around it. If one side of the garden is 10 meters, how long is the fence needed?

Answer: 500 points150m2=L*W150m2=L*10m 10m = 10mL=15m

P=2L+2W = 2(15m)+2(10m) = 30m+20m P = 50mThus, 5O m of fence is needed for 150m2 rectangular garden.
