Look at the angle in the picture and fill the table. Angle Right angle More than a right angle Less than a right angle

Given, The picture with angle marked. The angle bounded by two lines perpendicular to each other i.e. 90 ° is known as right angle. Thus, observing from the picture it is a right angle. Angle Right angle More than a right angle Less than a right angle Thus, the table is filled with the required answer.

Study the given figure carefully and match the following. Column I Column II (a) ∠ AOB ( i ) Straight angle (b) ∠ AOE ( i i ) Acute angle (c) ∠ AOC ( i i i ) Right angle (d) ∠ BOD ( i v ) Obtuse angle

Rohini made this shape. Mohini - Is it a closed shape or an open shape ? Rohini - It is a closed shape. Mohini - How many sides are there ? Rohini - It has 6 sides. Mohini made this. But it is not the same as the one made by Rohini. So Mohini tried again. This is what she made. Is there some way to say in what way these shapes are different ?

Given, A shape which is closed and has 6 sides. The shape made by Mohini has two closed shapes connected with each other. There are two triangles. But the shape made by Rohini is one closed shape. The name of the shape is Hexagon. The two shapes also differ in terms of the angles inside the shape. Hence, the two shapes are different.

Some angles are shown below: Which is the smallest and largest among these?

From the figure given in the question, We know that, Angles are formed by two rays lie in the plane having common end point. We observe that, ∠ OMN is the obtuse angle which is the largest angle among all the given angles. ∠ GHI is the acute angle, which is the smallest angle among all given angles. Hence, the largest angle is ∠ OMN and the smallest angle is ∠ GHI.
