STAAR PRACTICE QUESTIONS ON GEOMETRY FOR GRADE 4

Problem 1 :

Look at the figure.

Which term best describes the figure ?

A) Ray AB          B) Line segment AB

C)  Point AB        D) Line AB

Solution :

The given is not a line segment, because it is endless. It is line. So, it is line AB.

Problem 2 :

Look at the figures.

What is the total number of rays in the figures?

A)  2        B)  6      C)  5     D)  7

Solution :

AB, AD, AB are rays from the first figure. In the second picture, we have 4 rays. So, totally 7 rays.

Problem 3 :

 Look at the figure.

Which term best describes the figure?

A) Ray RST       B) Line segment RST

C) Angle RST    D) Point RST

Solution :

Angle RST

Problem 4 :

Which best describes parallel lines?

A) They intersect at one point.

B) They form one obtuse angle.

C They never meet.

D) They form one acute angle.

Solution :

The parallel lines will never meet. So, option C is correct.

Problem 5 :

Look at the figure

Which names an obtuse angle in the figure?

A)  ∠JHG    B) ∠FHJ    C) ∠GHK      D) ∠FHK

Solution :

A)  ∠JHG = acute angle 

B) ∠FHJ = acute angle

C) ∠GHK = acute angle

D) ∠FHK = straight line, 180 degree measure. So, it is obtuse angle.

Problem 6 :

Which type of angle is greater than a right angle?

A) Acute and obtuse only         B) Straight only

C) Obtuse and straight only    D) Obtuse only

Solution :

Obtuse angle will have angle measure more than 90 degree. Straight angle will have measure 180 degree, which is greater than 90. So, option C is correct.

Problem 7 :

Look at the figure.

Which names a straight angle in the figure below?

A) ∠ABC     B) ∠EBF    C) ∠CBF     D) ∠ABF

Solution :

∠ABF is a straight angle.

Problem 8 :

Which figure appears to show parallel lines?

Solution :

In option A, we have intersecting lines.

In option B, we have parallel lines because they are travelling in the same direction and distance between them will be equal.

Problem 9 :

Look at the figure.

What type of angle is ∠XYZ in the figure?

A) Acute angle    B) Straight angle

C) Right angle     D) Obtuse angle

Solution :

∠XYZ is a acute angle.

Problem 10 :

Look at the figure.

Which pair of lines appears to be perpendicular? 

A) JK and PR    B) LM and NO

C) NO and JK     D) PR and LM

Solution :

JK and NO are perpendicular. So, option C is correct.

Problem 11 :

Look at the angle made by the front of the arrow in the figure shown below

What type of angle is ∠R?

A) Acute angle         B) Obtuse angle

C) Right angle         D) Straight angle

Solution :

∠R is acute angle.

Problem 12 :

Which best describes perpendicular lines?

A) They form four right angles.     

B) They form one obtuse angle.

C) They never meet.     D) They form one acute angle

Solution :

If two lines are perpendicular, angle between them will be 90 degree.

In the picture above, we see 4 right angles. So, option A is correct.

Problem 13 :

Look at the figure.

Which angle in the figure is NOT an obtuse angle?

A) ∠JKF      B) ∠FGH     C) ∠HJK      D) ∠KFG

Solution :

∠KFG is a obtuse angle. So, option D is correct.

Problem 14 :

Look at the figure.

What type of angle is ∠FGC in the figure?

F) Acute angle      G) Straight angle

H) Right angle       J) Obtuse angle

Solution :

∠FGC is obtuse angle.

Problem 15 :

Look at the figure.

Which names a right angle in the figure?

A) ∠CDG     B) ∠EDF     C) ∠CDH     D) ∠FDH

Solution :

∠FDH is right angle.

Problem 16 :

Look at the figure.

Which two line segments in the figure appear to be parallel?

A) ST and RV         B) KN and LM

C)  MN and LM       D) LK and MN

Solution :

KL and NM are parallel lines because they are not intersecting each other and they are travelling in the same direction.

Problem 17 :

Look at the figure.

Which is a ray in the figure?

A) ML    B) LN     C) ON     D) MN

Solution :

LM and LN are line segments. MO is the line an NO is the ray.

Problem 18 :

Laila designed a banner for the math club. The shape of the banner is shown below

Which two line segments on the banner appear to be perpendicular to each other?

A) ST and RV        B) TU and VU

C) SR and TU       D) RV and SR

Solution :

RV and RS are perpendicular lines.

Problem 19 :

Look at the figure

Which names a right angle in the figure?

A) ∠STU     B) ∠TUR     C) ∠URS    D) Not here

Solution :

∠STU is obtuse angle

∠TUR is acute angle.

∠URS is right angle.

Problem 20 :

Look at the street map of the downtown area in a Texas town

Which street appears to be perpendicular to Pine Street?

A) Main Street     B) Oak Street    C) Elm Street   D) Not here

Solution :

Oak street and Pine street are parallel. 

Pine street and Main street are perpendicular. So, option A is correct.
