Angledle

Use the hints like a number game

After each guess you get a hot or cold hint and an arrow telling you to go higher or lower. Treat it like guessing a number. If 90 is too low and 135 is too high, try halfway, around 112. Splitting the range like this finds most answers inside six tries.

How to read an angle by eye

Angledle shows two lines meeting at a point and asks for the exact number of degrees. The answer can be any whole number from 1 to 359. Sort the angle into the right family first, then think about the exact number.

• Under 90 degrees is an acute angle. It looks narrower than the corner of a page.
• Exactly 90 is a right angle, the corner of a square.
• Between 90 and 180 is obtuse. The lines open wider than a corner but do not make a straight line.
• Over 180 is a reflex angle. Check which side the game is measuring, because the bigger side is the one you count.

Practice angles you can picture

Keep a few anchors in your head. Clock hands sit 30 degrees apart at one o'clock and 120 apart at four o'clock. Half a right angle is 45, and the corner of an equal sided triangle is 60. Comparing the screen to one of these is faster than guessing from nothing.

The daily angle changes at 6:00 AM your local time. If you want more practice before tomorrow, the unlimited mode gives you fresh angles with the same hints.
