### 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 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.

 equilateral triangle a triangle with equal length sides and equal angles isosceles triangle a triangle with two sides of equal length and two equal angles scalene triangle a triangle with all sides of different length and all angles of different size quadrilateral a polygon with four sides parallelogram a quadrilateral whose opposite sides are parallel rhombus a parallelogram with all four sides of equal length trapezium a quadrilateral with one pair of parallel sides parallel two lines or planes at equal distance from each other; they will never meet perpendicular a line at a 90 degree angle to another line hypotenuse the longest side of a right angle triangle

a triangle with all sides of different length and all angles of different size

a line at a 90 degree angle to another line

the longest side of a right angle triangle

a polygon with four sides

two lines or planes at equal distance from each other; they will never meet

a triangle with two sides of equal length and two equal angles

a quadrilateral whose opposite sides are parallel

a parallelogram with all four sides of equal length

a triangle with equal length sides and equal angles

a quadrilateral with one pair of parallel sides

• Question 1

a triangle with all sides of different length and all angles of different size

scalene
scalene triangle
EDDIE SAYS
The -ene ending is tricky here.
• Question 2

a line at a 90 degree angle to another line

perpendicular
perpendicular line
EDDIE SAYS
The ending is -ar, not -er.
• Question 3

the longest side of a right angle triangle

hypotenuse
EDDIE SAYS
It is usually the ending that causes problems with this word, too.
• Question 4

a polygon with four sides

EDDIE SAYS
This word is easier to spell if you sound out the separate syllables.
• Question 5

two lines or planes at equal distance from each other; they will never meet

parallel
parallel lines
EDDIE SAYS
It is double 'll' in the middle of this word but there is only one 'l' at the end.
• Question 6

a triangle with two sides of equal length and two equal angles

isosceles
isosceles triangle
EDDIE SAYS
The 'sc' in the middle of this word is tricky.
• Question 7

a quadrilateral whose opposite sides are parallel

parallelogram
EDDIE SAYS
If you can spell 'parallel' then this is not too difficult.
• Question 8

a parallelogram with all four sides of equal length

rhombus
EDDIE SAYS
Don't forget the 'h' in this word.
• Question 9

a triangle with equal length sides and equal angles

equilateral
equilateral triangle
EDDIE SAYS
This begins equil- even though the word 'equal' is spelt with an 'a'.
• Question 10

a quadrilateral with one pair of parallel sides

trapezium
EDDIE SAYS
There is only one 'e' in the middle of this word.
