arctrig

I do love that the arctrig functions do translate to actual arc lengths, though.

The arrangement of squares is as follows:
Taking point A as the origin, with the squares building upwards from the first row. 
2 squares on row 1, where A is the bottom left corner of first square.
2 squares on row 2, starting above the 2nd square of row 1.
Point B is the bottom right corner of the 2nd square of row 2.
1 square on the row 3, above the 2nd square of row 2.
3 squares on row 4, with the middle square above the square of row 3.
1 square on row 5, above the 1st square of row 4.
Point C is the top right corner of the top square.

Here is today's #OCRMathsPuzzle.

Several square blue tiles with side length 2 m are arranged as shown below.
Points A, B and C are marked on vertices of the tiles.

What is the area of the triangle ABC?

I am not sure why there wasn't a set of exercises on speed till now... That's speed/distance/time just in case you'd taken that the wrong way!

Self-marking = more time to address misconceptions.

Mathematical Miscellany #101 A compilation of mathematical goodies! It is so important that students check answers for reasonableness, yet they frequently don't. Examiners frequently report that students lose "easy" marks by providing answers that are physically or mathematically impossible. Checking answers can make a difference in students' grades. For example, always sanity-check real-world results. I once had a student calculate an individual’s height as 4 cm.
