QUESTION 1 of 10

Spelling is often thought of as a skill needed for English lessons, but many words in other subjects are tricky to spell, and it can be frustrating if you know the word you want to write but don't know how to spell it.

In this worksheet you can practise spelling some more of the terms you will come across in your maths lessons when you are working in the area of shape, space and measures.

Read the following terms and their definitions and try to remember the spellings.

 perimeter the distance around the edge of a polygon circumference the perimeter of a circle protractor an angle measurer acute angle an angle less than 90 degrees obtuse angle an angle more than 90 degrees but less than 180 degrees reflex angle an angle more than 180 degrees but less than 360 degrees equidistant point a point at equal distance from two or more other points congruent shapes shapes that are the same in every way apart from their position complementary angles two angles with a sum of 90 degrees supplementary angles two angles with a sum of 180 degrees

an angle measurer

shapes that are the same in every way apart from their position

the distance around the edge of a polygon

two angles with a sum of 90 degrees

an angle less than 90 degrees

a point at equal distance from two or more other points

an angle more than 90 degrees but less than 180 degrees

the perimeter of a circle

an angle more than 180 degrees but less than 360 degrees

two angles with a sum of 180 degrees

• Question 1

an angle measurer

protractor
EDDIE SAYS
The ending is -or, not -er.
• Question 2

shapes that are the same in every way apart from their position

congruent
congruent shapes
EDDIE SAYS
This is easier to spell if you sound out the separate syllables.
• Question 3

the distance around the edge of a polygon

perimeter
EDDIE SAYS
The ending is -er even though the word 'metre' ends in -re.
• Question 4

two angles with a sum of 90 degrees

complementary
complementary angles
EDDIE SAYS
The ending is -ary, not -ery, and watch the 'e' in the middle of the word, too!
• Question 5

an angle less than 90 degrees

acute
acute angle
EDDIE SAYS
Remember that 'acute' is one word, not two.
• Question 6

a point at equal distance from two or more other points

equidistant
equidistant point
EDDIE SAYS
This is easier to spell if you sound out the separate syllables.
• Question 7

an angle more than 90 degrees but less than 180 degrees

obtuse
obtuse angle
EDDIE SAYS
There is only one 's' in this word.
• Question 8

the perimeter of a circle

circumference
EDDIE SAYS
The beginning of this word is the same as the beginning of 'circle'.
• Question 9

an angle more than 180 degrees but less than 360 degrees

reflex
reflex angle
EDDIE SAYS
This words ends in -x.
• Question 10

two angles with a sum of 180 degrees

supplementary
supplementary angles
EDDIE SAYS
The 'e' in the middle of this word can be hard to remember, and the ending is -ary, not -ery.
