Angles & Triangles

“ What type of angle is this? What do you estimate the size to be? ” straight angle exactly 180 °

This is a 360 ° protractor. You can use the letter placed around the protractor to write secret codes. What letter is at L clockwise 150 ° ? What letter is at i anticlockwise 250 ° ? What is the angle from 0 ° to H clockwise ? Obtuse se Angel

whether the total angle on the triangle is 180 ° ? Total angles in triangle equal with straight angle

Type of Triangles By Angles we can classify them by: By Sides we can sub classify triangles in:  Equiangular  Right  Acute  Obtuse Then, we can combine both classifications and get some other results including acute isosceles triangle, acute scalene, right scalene and so on

Right-Angled Triangles Right-Angled Triangles can be either Isosce les or scalene triangles

Now you must complete the question in your learners book on page 109 number 1 page 111 number 4 page 112 number 1 and 2 . Angels & Triangles
