Today, we are continuing with angles, however, we are going to learn how to work out the missing angle in triangle.
Starter:
Letβs recap on each type of triangle:
All 3 angles in a triangle will always add up to 180 degrees.
Be careful with each type of triangle, your knowledge about them will help you solve missing angles.
Activity:
I can find the missing angles.
All angles in an equilateral are the same.
So letβs have a look at right angled triangles. We know what one angle should be already from the name.
We know a right angle is 90 degrees.
We are given another angle.
We have to work out the final angle.
So take it step by step.
All three must = 180
- We have 90 degrees + 55 degrees = 145
Therefore, 180 degrees β 145 degrees = 35 degrees.
The missing angle is 35 degrees.
Now try b, c and d.
Challenge:
Draw your own example for a right angled triangle with a missing angle.
Give them to someone to try and work out (send a photo to a friend or give to a family member, or send them to me. π©π»βπ«

Literacy
There are so many superheroes helping our country right now.
Have a look at this picture below and choose which questions you would like to answer. (Choose at least 4, you can of course do them all if you wish π).
- What do you think the phrase, βA picture is worth a thousand wordsβ mean?
- List the names of the superheroes you can see in the image.
- What message is the creator of this image trying to get across?
- Can you create a title for the image?
- Add speech bubbles or thought clouds to the image or write them beside the names from question 2.
- Vocabulary challenge- use the image to help you generate at least 3 nouns, adjectives, verbs, adverbs and at least 1 simile or metaphor.
- Use some of the vocabulary to write a caption for the image.
- Draw a picture of your own version of an NHS superhero and post on our school Twitter account using #nhsscotland to show your gratitude for all their hard work.
*Challenge*
Create a storyboard, story of film incorporating either the image above or your own version or a superhero.
Please share your work, as I know itβs going to be super.
