- complete the following task
Process
- step1:open the task and answer all the question neat and eligibly.
- step2:In this task you are allowed to use different formulas as long as the answer will be correct.
- step3: Don't forget to use the square roots.
- step4:measure the units appropriately.
- step5:draw the diagram because sometime you will provided with a word sum so in order for to understand what is expected from you draw the diagram so that you can have a clear picture of the question.

Conclusion
- well done and thank you for completing the task.
- a right angle triangle can be identified given the length of the longest side squared is equal to the sum of the other two sides squared. the length of any side of a right angled triangle can be determined given the length of any two sides.
- in conclusion learners should develop strategies for dealing with problems, develop capacity for logical explanation.
- reflection
- Thank you for completing your task now its time to tell what you have learnt on the lesson.
Credits
each question is out of 4 marks and the total of the task is 20 marks.
i will issue a smaller mark if your formula is correct maybe 1 mark depending on how you wrote your formula even if your final answer is incorrect.
