What Is the Obtuse Angle Triangle Area Set Used For?
The formula does not change — area equals half the base times the height — but in an obtuse-angled triangle the height drawn from either of the two acute corners lands outside the triangle, on the base line extended beyond the triangle. Students often measure a slanting side instead of the true perpendicular height, so working through this case in the maths lab helps them see that the height is always measured at right angles to the chosen base. The topic belongs to the area of triangles in middle-school mensuration, for example class 7 Perimeter and Area.
What to Specify When Ordering
- Quantity — the number of sets for your classes or maths lab.
- Matching sets — the acute-angle and right-angle triangle area sets are separate items that can be included in the same quotation.
Frequently Asked Questions
What is the Area of Obtuse Angle Triangle set used for?
Teaching the area of an obtuse-angled triangle in maths lessons and practical maths lab work.
How many parts are in the set?
The set has 3 parts.
Why is the obtuse-angled triangle treated separately?
Because the perpendicular height from an acute corner falls outside the triangle, so the base has to be extended to meet it. The area is still half the base times that height.
How does it differ from the acute and right angle triangle sets?
It covers the obtuse-angled triangle. The acute-angle set also has 3 parts, while the right-angle set has 4 parts.
Who manufactures the set?
JLab, the trading name of Jain Laboratory Instruments Pvt Ltd, at its works in Ambala, Haryana, India.
OEM Manufacturer
JLab is the trading name of Jain Laboratory Instruments Pvt Ltd, which manufactures maths lab equipment and school lab equipment in India; the company was incorporated in 2017 and is based on Hargolal Road, Ambala, Haryana. Sets like this one are made in JLab’s own works and are not bought in from traders, so schools, dealers and importers get them straight from the manufacturer, which also handles repeat orders. JLab exports worldwide and ships to buyers in every region — for example Cambodia in Southeast Asia, Croatia in Southern Europe, Rwanda in East Africa, Romania in Eastern Europe and Kyrgyzstan in Central Asia.
