4 IN A ROW game to practice
'Angles: acute or obtuse' for 3rd grade

Identify angles: acute, obtuse or right angle

This topic requires you to identify the type of angle illustrated in each question. The three types of angle you will identify are acute, obtuse and right angles.

An acute angle is an angle that measures less than 90°.
For example, ∠30°, ∠40°, ∠57° are all acute angles.

An obtuse angle is an angle that measures more than 90° and less than 180°. Obtuse is another word for stupid, but these angles are not stupid...
Examples of obtuse angles include ∠130°, ∠108° and ∠179°.

A right angle is an angle that measures exactly 90°. It has a special square symbol when shown diagramatically as opposed to the curved arc of other angles.


Note: You may also sometimes come across a 'straight angle' in text books - that is an angle of exactly 180°.

With our Four in a row math game you will be practicing the topic "Angles: acute or obtuse" from 3rd grade / Shapes / Angles. The math in this game consists of 16 questions that ask you to identify whether the given angles are acute angles, right angles or obtuse angles.

Four in a row is similar to the paper game "Noughts and crosses" but we have changed it into a one-person math learning / revision game. The aim of the game is to win 4 cells in a row from a grid of 16 cells.
