Geometry Chapter 1

Lines

100

What is one-dimensional figure consist of one endpoint and arrowhead that extended without end?

the Ray

200

Where do two lines intersect at? and where do two planes intersect at?

Lines intersect a point and planes intersect at line.

300

What is the point on segment that divides the segment into two congruent segment?

the midpoint

400

What is a point, ray, line, segment, or plane that intersects the segment to divide it into two congruent segments?

A segment bisector.

500

How do we get distance from one coordinate point to another coordinate point on coordinate plane?

Using distance formula.

Angle

100

What is an angle with degree between 90 and 180 called?

Obtuse angle.

200

What are the two different name for angle OPQ?

angle QPO or Angle P

300

If an angle bisector bisects 174^o angle, classify the angle created by the angle bisector and calculate its measure.

Acute angle, 87^o

400

If an angle bisector bisects a angle with 150^o, what are the measure of two new angle?

75^o

500

The measure of angle ABC is 140. If angle ABD is 11x-10 and angle DBC is 5x+6, find both angles. 

x=9

ABD=89^o, DBC=51^o

Angle relationship

100

What are angles sum up to 90 degree called?

Complementary angles. 

200

Given angle 1 and angle 2 are linear pairs, what is the sum of angle 1 and angle 2?

180^o

300

Angle 1 and angle 2 are vertical angle. Given that angle 1 is 70^o, find angle 2. 

70^o

400

Angle 1 and angle 2 are complementary angle. Given angle 1 is 35^o, find angle 2.

55^o

500

angle 1 and angle 2 are supplementary angles. Given angle 1 is 5x+5 and angle 2 is 4x-23, find x.

x=22

Polygon

100

What is the formula to get area of a triangle. 

Base * Height / 2

(B*H)/2

200

What is a regular polygon?

Polygon that is both equilateral and equiangular.

300

How can we classify this an arrow figure as a polygon?

(➡️)

Concave heptagon

400

How do we calculate the perimeter of a polygon on coordinate plane?

Use distance formula to get the measure of each sides and sum all of the sides together. 

500

Draw a concave polygon with ten sides and a convex polygon that has sides of half the number concave polygon.

Draw

Circle

100

What is a perimeter or a distance around a circle is called?

Circumference

200

What is D stands for in circumference formula?

Diameter.

300

What is the ratio between the circumference and the diameter of a circle called?

A pi

400

What is the area of a circle with diameter of 20cm?

100pi cm² or 314.2 cm².

500

If the circumference of an circle is 16ft, what is the area of the circle to the nearest tenth?

20.3 ft².
