Test: Lines, Angles & Triangles - 1 - Class 5 MCQ

• As shown in above figures, figure 2, figure 4 and figure 5 are the figures which has  the pair of parallel lines
• Hence the correct answer is option B 

• Here, 6 pairs of perpendicular lines are CB⊥ AB, BC ⊥ CD, ED ⊥ CD, DE⊥ EF, FG⊥ EF and FG ⊥ HG.
• Hence Jyoti made the correct statement..
• 

• The first letter is M. It is made of 4 lines intersecting at 3 points. We can see that none of the angles are right angles. So M don’t have any perpendicular lines.
• The next letter is A. It has 3 lines intersecting at 3 points and no lines are perpendicular. So don't have any perpendicular lines.
• Let us consider T. It has 2 lines which meet at one point. From the letter we can say that the 2 lines are perpendicular. So T has perpendicular lines.
• Now we have H. It has 2 parallel lines intersected by a line. From the figure we can say that the intersected line is perpendicular to the parallel lines. So H also has perpendicular lines.
• The last letter is S. It doesn’t have a straight line or any intersection. So it doesn’t have any perpendicular lines.
• So only the letters T and H have perpendicular lines.
• So only 2 of the given letters have perpendicular lines.

• Any angle which is larger than 180º but smaller than 360º is called as a reflex angle.
• Here, the angle shown is larger than 180º but smaller than 360º. 
• Hence, it is a reflex angle.
• Therefore, option C is correct.

• 
• As we can see , it is an acute angle

• Measure of angle Q is more thaan 90º but less than 180º.
• Hence the ∠Q is an obtuse angle.

An obtuse angle is an angle which is greater than 90° and less than 180°. In other words, an obtuse angle is between a right angle and a straight angle.
Some examples of Obtuse angles are: 

A right angle forms a perfect "L" shape and measures 90 degrees. Any angle greater than this is called an obtuse angle, which appears more open or wider than a right angle. 

• An obtuse angle is an angle whose measure is greater than 90 degrees but less than 180 degrees.

The correct answer is:

a) One point

Intersecting lines cut each other at exactly one point.
