Basic geometry worksheets - Solution

Problem 1 :

Look at the figure given below and answer the questions. 

(i) Name three points that are collinear. 

(ii) name four points that are coplanar. 

(iii) Name three points that are not collinear.

Solution :

Solution (i) : 

Points D, E and F lie on the same line. So they are collinear.

Solution (ii) : 

Points D, E, F and G lie on the same plane. So they are coplanar. D, E, F and H are coplanar, even though the plane containing them is not drawn.  

Solution (iii) : 

There are many correct answers. For instance, points H, E and G do not lie on the same line. 

Problem 2 :

Sketch the next figure in the pattern.

Solution : 

Each figure in the pattern looks like the previous figure with another row of squares added to the bottom. Each figure looks like a stairway. 

So, the sixth figure in the pattern must have six squares in the bottom row. 

Problem 3 :

Use the map to find the distances between the three cities that lie on a line. 

Solution : 

Using the scale on the map, we can estimate that the difference between Athens and Macon is 

AM  =  80 miles

The distance between Macon and Albany is 

MB  =  90 miles

It has been explained in the picture given below.

Knowing that Athens, Macon and Albany lie on the same line, we can use the Segment Addition Postulate to conclude that the distance between Athens and Albany is 

AB  =  AM + MB

AB  =  80 + 90

AB  =  170 miles 

It has been explained in the picture given below.

Problem 4 : 

Each eye of a horse wearing blinkers has an angle of vision that measures 100°. The angle of vision that is seen by both eyes measures 60°.

Find the angle of vision seen by the left eye alone. 

Solution : 

We can use the angle addition postulate. 

m∠2 + m∠3  =  100°    (The total for left eye is 100°)

m∠3  =  100° - m∠2    (Subtract m∠2 from each side)

m∠3  =  100° - 60°    (Substitute 60° for m∠2)

m∠3  =  40°    (Subtract)

Hence, the vision for the left eye alone measures is 40°.

Problem 5 :

Find the coordinates of the midpoint of AB with endpoints A(-2, 3) and B(5, -2). 

Solution :

Use the midpoint formula. 

Here, 

(x, y)  =  A(-2, 3)

(x, y)  =  B(5, -2)

Then, the midpoint of AB is 

=  [(-2+5)/2, (3-2)/2]

=  (3/2, 1/2)

It has been illustrated in the picture given below.

Problem 6 :

In the diagram shown below, RQ bisects ∠PRS. The measures of the two congruent angles are (x + 40)° and (3x - 20)°. Solve for "x".

Solution :

Congruent angles have equal measures.

m∠PRQ  =  m∠QRS

Substitute given measures.

(x + 40)°  =  (3x - 20)°

Add 20° to each side. 

x + 60  =  3x

Subtract x from each side.

60  =  2x

Divide each side by 2.

30  =  x

So, x = 30. We can check by substituting to see that each of the congruent angles has a measure of 70°.
